Opis:: The article describes the simple way of BLDC motor control development in the Simulink environment. This way of development is also called Model Based Design approach, which is nowadays rapidly gaining popularity. MBD should be very effective method for development time reduction and finds usage especially during fast prototyping phase. The simple BLDC motor controller has been created and presented in this paper. Because the Simulink itself cannot control any outside system or process itself, a real special software and hardware has to be connected to the personal computer. Described control algorithm has been developed for dSPACE environment with appropriate power and interface electronics. The sinusoidal control algorithms for low power sensor BLDC motor has been used.

Opis:: The paper presents a water balance of a flow-through, dammed lake, consisted of the following terms: surface inflow, underground inflow/outflow based on the Dupuit’s equation, precipitation on the lake surface, evaporation from water surface and outflow from the lake at which a damming weir is located. The balance equation was implemented Matlab-Simulink®. Applicability of the model was assessed on the example of the Sławianowskie Lake of surface area 276 ha and mean depth - 6.6 m, Water balances, performed for month time intervals in the hydrological year 2009, showed good agreement for the first three months only. It is concluded that the balancing time interval should be shorter (1 day) to minimize the errors. For calibration purposes, measurements of ground water levels in the vicinity of the lake are also recommended.
Praca przedstawia bilans wodny przepływowego piętrzonego jeziora, uwzględniający dopływ powierzchniowy, dopływ i odpływ podziemny opisany równaniem Dupuita, opad na powierzchnię jeziora, parowanie z powierzchni wody oraz odpływ w przekroju zamkniętym jazem piętrzącym. Z uwagi na nieliniowe związki wymienionych składników bilansu z poziomem wody w jeziorze, do obliczeń wykorzystano program komuterowy Matlab-Simulink®. Przydatność modelu sprawdzono na przykładzie Jeziora Sławianowskiego o powierzchni 276 ha i średniej głębokości - 6,6 m. Jezioro to zostało podzielone na dwa akweny o zróżnicowanej głębokości. Wyniki obliczeń miesięcznych bilansów wodnych dla roku hydrologicznego 2009, wykazały dobrą zgodność z pomiarami jedynie dla trzech pierwszych miesięcy. Stwierdzono, że dla zmniejszenia błędów obliczeniowych należałoby skrócić interwał bilansowania do jednej doby. Kalibracja modelu byłaby łatwiejsza i bardziej adekwatna, gdyby do oszacowania przewodności hydraulicznej przyległych do jeziora gruntów i osadów dennych wykorzystać badania poziomów wody w piezometrach, zlokalizowanych w kilku transektach, prostopadłych do linii brzegowej jeziora.

Opis:: The main aim of the paper is to present a developed methodology of simulation of the energy efficiency of a selected energy storage unit. The authors focused their actions on batteries that could be the base for an energy storage system possible to apply in a modernized hybrid-shunting locomotive. Three different nickel-cadmium batteries were selected as representatives for the study. Simulation was focused on repeated cycles of charging and discharging the batteries. The simulation model generally consists of three main components: a specified load cycle, a dynamic model of the DC electrical machine and a model of the Ni-Cd battery. The input data for the battery model is based mostly on the parameters provided by the manufacturer data sheets. However, an internal resistance had to be measured for each battery. Conducted simulations provided information about the electromotive force, state of charge, an average efficiency of the battery, as well as the temperature changes during the cycle. The proposed approach to the battery simulation can be also applied for the loading cycles similar to those that occur during the actual operation of the locomotive. The current study is a part of the project focused on modernization of the diesel-electric shunting locomotive to the hybrid one.

Opis:: This paper presents simulation models of a grid-connecting converter for photovoltaic applications using MATLAB/Simulink’s Simscape SimPowerSystems toolbox. Manufacturers of these converters often do not provide any information related to the topology and control algorithms, thus impeding the modeling. Simulation models of two possible topologies of SVM based current controlled three-phase converters are shown and compared. The simulation results are compared to a 9.6 kW rooftop PV plant built in Novi Sad, Serbia, by connecting a corresponding PV array model at the input of the converter models. Simulation results have shown, that the created models produce results similar to the physical system, and that both modelled topologies are possible and viable to implement.

Opis:: This paper is focused on increasing the power quality of Unique Macaroni factory, located in Bahir Dar Town. Necessary data have been collected from the factory and the collected data are analysed. Based on the analysis of data, it is found that the factory working power factor is low and hovering around 0.7125. Voltage variations are up to 9.09%, average voltage unbalance is 2.2% and total harmonic distortion (THD) of load currents and voltage are 24.17% and 10.16%, respectively. Harmonic components have existed in the power distribution system of the factory. Based on the analysis of power quality problem in the factory, distribution static compensator (DSTATCOM) and its control system have been designed to boost power quality of the factory and the results are obtained by generating simulations using Matlab software. It is observed from outputs of the Matlab simulations that DSTATCOM can improve the power quality of the factory. Generally, the shape of the waveform of load voltage and current is improved and THD level of load voltage is minimised to 1.55% and load current THD level is 7.09%. The reactive power needed by the loads (442 kVAr) is almost provided by the DSTATCOM, so reactive power from source supply is very small such as 22 kVAr so that the power factor of the source tends to unity.

Opis:: This paper presents the method of calculation of the electric and magnetic fields under overhead transmission line with any number of circuits, phase positions, voltages and current loads. Calculations of this type usually require specialized and costly programs. The program EMTP/ATP is a royalty free tool to calculate the electric transient and steady states in complex power systems. You can use this program and through appropriate modeling the multi-phase wire system representing the line and measurement device calculate the strength of the electric and magnetic fields. The results of calculations are characterized by a very small error compared to the results obtained by using the specialized commercial program. This method can be used with other popular engineering tools like Matlab/Simulink or PSCad.

The model contains the mathematical model of the induction machine recorded as an S-function and the connecting blocs attaching the model from one side to the three phase terminals of the supply system model and from the other to the system of mechanical model. Hence, SimPowerSystems and SimMechanics libraries can be used. Such a methodology allows for various drives modelling were the induction machine operates as a motor or a generator and cooperates with power electronics. Using wide range of Simulink possibilities various control techniques can be applied. Using this methodology the own mathematical models of other electrical machines together with the Simulink library models can be used.

Opis:: This paper presents the experimental research and simulating results of a ZM130 hydrodynamic torque converter under steady and unsteady working conditions with an external step signal and sinus on turbine’s shaft on a modified test bench. The mathematical model of torque converter was described by the one-dimensional flow theory with variable loss coefficients. The character of received equations from test bend showed by linearized transmittance functions with variable coefficients. For test bend object identification researches will be used an Identification Toolbox from a mathematical code in Matlab, which enables to create transfer functions as a linear model from measurements data as they got the highest correctness level with input signal (as they get the best correction level with input signal on the pump´s shaft). This mathematical model for dynamic loads will be verified by experimental tests. The aim of the carried out studies was determination the effect of sampling time decreasing on the quality of measured parameters. Results of present investigations were compared with those obtained earlier, but for the same input signals .It is possible to affirm that proposed theoretical model imitates the change of dynamic parameters, and the same the property of the torque converter. Researches led on the test bend with extortion input torque sinus signal on the turbine’s shaft confirmed correctness of this model.

Opis:: It can be considered that the suspension system is one of the most important systems in the VEHICLE. Where it is responsible for the stability and balance of the vehicle’s structure on the roads and curves to ensure the comfort of passengers. Also, it absorbs the shocks resulting from the unevenness of the road and prevents it from reaching the wheelhouse. The influence of the suspension constructive parameters in order to obtain the smallest level of displacements of the sprung mass has been investigated. The following control parameters are the stiffness of the sprung, unsprung mass, and the damping of the sprung mass. The parameter which affects most displacements of the sprung mass was determined by applying the analysis of variance (ANOVA). The investigation was conducted using MATLAB/SIMULINK software, and a line model of a quarter of the vehicle was created. It was determined that the stiffness of sprung has the most significant influence on the displacement of the sprung-mass, which further affect the vehicle’s comfort.

Opis:: The use of direct drives in linear and rotary axes as well as increased power density of main drives offer the potential to raise feet rate, acceleration and thus allow higher productivity of machine tools. The induced heat flow rates of these drives could lead to thermo-elastic deformations of precision related machine tool components. In order to reduce thermally caused displacements of the tool-center-point and to prevent a negative impact on the achievable accuracy, the induced heat flow rates of main drives must be dissipated by effective cooling systems. These systems account for a major share of the machine tool’s total energy consumption.With the intention to overcome the area of conflict regarding productivity and energy efficiency, a so called thermoelectric self-cooling system has been developed. To convert a proportion of thermal losses into electrical energy, thermoelectric generators are placed in the heat flow between the primary part of a linear direct drive and the cooling system. The harvested energy is directly supplied to a pump of the water cooling circuit, which operates a decentralised cooling system with reasonable coolant flow rates. For predicting the thermoelectric system behaviour and to enable a model-based design of thermoelectric self-cooling systems, a thermal resistance network as a system simulation in MATLAB/Simulink is presented. The model is applied to a feed unit with a linear direct drive and allows the calculation of harvested energy as well as the simulation of steady and transient states of the cooling system. The comparison of simulative and experimental determined data indicates a predominantly high model prediction accuracy with short simulation times. At an early stage of development the model turns out to be a powerful tool for design and analysis of water flow thermoelectric self-cooling systems.
