Opis:
This article, which is a continuation of the article under the same main title and subtitle: part 1 Design and its implementation, includes the obtained results of research experiments with the use of a designed and implemented racing game. It uses a neural model of the vehicle motion control system on the racetrack in the form of a Perceptron Artificial Neural Network (ANN). In designing the movement of vehicles on the racetrack, the following were used, inter alia, Godot Engine and MATLAB and Simulink programming environment. The numerical data (14 input quantities and two output quantities) for ANN training were prepared with the use of semi-automatic measurement of the race track control points. This article shows, among others, the results of 10 selected research experiments, testing and simulation, confirming the correct functioning of both the computer game and the model of the neural control system. As a result of simulation tests, it turned out that the longest lap of the track in the conducted experiments lasted 4 minutes and 55 seconds, and the shortest - 10.47 seconds. In five minutes, the highest number of laps was 34, while the lowest numbers of laps were 1 and 5. In the course of the experiments it was noticed that under the same conditions the ANN learning outcomes are sometimes different.

Opis:
W artykule przedstawiono możliwości zastosowania zintegrowanego środowiska programistycznego MATLAB&Simulink do komputerowej symulacji wybranych układów sterowania. MATLAB (MATrix LABoratory) to program komputerowy będący interaktywnym środowiskiem do wykonywania obliczeń naukowych i inżynierskich, służącym do tworzenia symulacji komputerowych, zaś Simulink to część pakietu numerycznego MATLAB dający możliwość symulacji komputerowych modeli przy pomocy interfejsu graficznego oraz tzw. bloków. W artykule podano przykłady symulacji rozwiązań równań różniczkowych zwyczajnych, wyznaczania różnych typów charakterystyk częstotliwościowych; badania stabilności układów na podstawie kryterium Hurwitza i Nyquista; badania stabilności, sterowalności i obserwowalności układów wielowymiarowych; wyznaczania portretu fazowego oraz regulacji dwupołożeniowej.
The paper presents the possibilities of using the integrated environment of MATLAB&Simulink for computer simulation of selected control systems. MATLAB (matrix laboratory) is a multi-paradigm numerical computing environment and fourth-generation programming language. A proprietary programming language developed by Math-Works, MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages. Simulink, also developed by MathWorks, is a graphical programming environment for modeling, simulating and analyzing dynamic systems. It offers tight integration with the rest of the MATLAB environment and can either drive MATLAB or be scripted from it. The paper shows examples of solutions of ordinary differential equations, determination of different types of frequency characteristics, system stability tests based on the Hurwitz and Nyquist criteria, stability testing, controllability and observability of multidimensional systems, creation of phase-portrait and study of two-position control.

Opis:
In the study the method of modelling of the photovoltaic system (PV) in MATLAB & SIMULINK environment was presented along with test results of the impact of shading on the value of energy output from the photovoltaic system. The PV system model constructed of five parallel connected photovoltaic panels of TPSM6U type was proposed. Simulation tests were conducted considering the effect of poor and strong shading of panels causing differences in the density of the radiation power (irradiance) for individual panels and the PV system. The values of electrical energy generated by individual PV panels and the whole photovoltaic system were determined for the purposes of the actual forces. Optional switching on and off of the bypass diodes was considered in the photovoltaic panels. The tests were developed and final conclusions were formulated.

Opis:
The paper presents a method of modelling photovoltaic (PV) cells in the MATLAB & SIMULINK environment. A two-diode photovoltaic cell structure was developed, featuring series resistance. Measurements of a PV panel were carried out to determine the value of series resistance, open circuit voltage, and short-circuit current. The model suggested was used to operate the ST-STP020S-12/Cb panel with an actual input function (measurements of solar radiation power density of the south-east area of Poland in 2011). Simulation experiments were conducted of the system modelled to determine current changes, power changes, electric energy production, voltage-current characteristics, and to come up with results and draw final conclusions.

Opis:
Publikacja ma charakter naukowo-techniczny i poświęcona jest modelowaniu oraz symulacji pracy generatora wiatrowego w postaci rzeczywistej turbiny wiatrowej o mocy 1,6 kW firmy Travere Industries z systemem magazynowania energii w środowisku MATLAB & SIMULINK. W pracy przedstawiono algorytm implementacji modelu z doborem elementów, które można warunkowo podzielić na dwa podsystemy. Pierwszy podsystem to model, który symuluje turbina wiatrowa za pomocą układu turbina-generator. Zastosowano w nim dwa bloki, z których jeden pełni rolę generatora PMSG, który na wyjściu generuje trójfazowy prąd przemienny (prąd stały dla obciążenia uwzględniono poprzez konwerter mostkowy). Drugi podsystem realizuje magazynowanie energii poprzez dwukierunkową przetwornicę DC/DC, która umożliwia oddzielenie akumulatora od szyny obciążenia. Model turbiny wiatrowej zaimplementowano w środowisku SIMULINK. W artykule przedstawiono oscylogramy z wynikami, uzyskanymi na podstawie symulacji dla różnych wartości prędkości wiatru. Przeprowadzono dokładną analizę otrzymanych wyników badań. Artykuł kończą podsumowanie i wnioski.
The publication is of a scientific and technical nature and is devoted to modeling and simulating the operation of a wind generator in the form of a real wind turbine 1.6 kW from Travere Industries with an energy storage system in the MATLAB & SIMULINK environment. The paper presents the model implementation algorithm with the selection of elements that can be conditionally divided into two subsystems. The first subsystem is a model that simulates a wind turbine with a turbine-generator system. It uses two blocks, one of which acts as a PMSG generator that generates three-phase alternating current at the output (direct current for the load is accounted for through a bridge converter). The second subsystem performs energy storage via a bi-directional DC / DC converter, which allows the battery to be separated from the load bus. The wind turbine model was implemented in the SIMULINK environment. The article presents oscillograms with the results obtained on the basis of simulations for various values of wind speed. A thorough analysis of the obtained test results was carried out. The article ends with a summary and conclusions.
