Opis:: W artykule wskazano, że napędy hybrydowe i elektryczne, oprócz znanych walorów ekologicznych, są szczególnie korzystne do budowania zaawansowanych systemów sterowania napędem kół, które wpływają na kierunek ruchu pojazdu (Torque Vectoring). Wychodząc od opisu złożonej budowy takich systemów w pojazdach napędzanych silnikiem spalinowym stwierdzono, że w przypadku napędzania kół silnikami elektrycznymi, realizacja funkcji takiego systemu jest prostsza. Omówiono zasadnicze rodzaje i przykłady takich konstrukcji, uwypuklając różnice w ich strukturze oraz występujące problemy i ograniczenia. W podsumowaniu podkreślono ważność tego aspektu napędzania kół silnikami elektrycznymi, co przekłada się poprawę bezpieczeństwo czynnego pojazdów.
The paper indicated that hybrid and electric drivetrains, besides its well known ecological values, are particularly advantageous for designing advanced systems of wheel control, which influence the direction of vehicle’s motion (Torque Vectoring). Starting from the description of complex systems meant for combustion engine powered vehicles, it was stated that when wheels are propelled by electric motors, realization of such system is simpler. The basic types and examples of such designs were reviewed; and their structure, associated issues and limitations were emphasized. The summary underlined the importance of this aspect of electric motor propulsion, which translates into improved active safety of vehicles.

Opis:: This paper deals with a comparative study using numerical simulations between the failures effect caused by the speed sensor faults for a propulsion control system (PCS) of an electrical vehicle (EV) using dualinduction motors structure. The PCS strategies are achieved on two types of controls where the first one is done from a flux-oriented control (FOC) and the second one is conducted from a direct torque control (DTC). For an electric vehicle, we will often guarantee service continuity, in spite of the occurred faults such as an offset fault in speed sensor and a zero-feedback sensor speed fault which both are essentially needed in the structure of the PCS-EV. The occurred fault cited above might influence one of the dual induction motors which could be conducted an unbalance in the dual used motors and from which the control of the vehicle might be also lost. The results of the realized numerical simulations on the EV conducted by the PCS demonstrate clearly the impact of the so-called-fault. Thereafter, we can also appreciate the robustness using each used control propulsion system in despite of the occurred speed sensor fault.

Opis:: This paper presents an analysis of environmental and technical conditions necessary for working out a possibly most favourable propulsion system for a two – segment passenger ship intended for navigation between Berlin and Kaliningrad. There are presented various types of propulsion systems for small ships as well as analyzed their possible applications and consequences. In this work there were taken into account system’s reliability, efficiency, dimensions, mass and costs of manufacturing, assembling and possible replacing the system components as well as an impact on maneuverability and natural environment. With taking into account the above mentioned criteria it was finally found that the diesel-hydraulic system fitted with two azimuthal ducted solid propellers is the most favourable. There are also presented a schematic propulsion and control diagram, three-dimensional arrangement drawing of system components as well as assembly drawing of the designed azimuthal propulsion system.

Opis:: The paper deals with synthesis of automatic control system for an unmanned underwater robotic vehicle. The problem of determining permissible propulsive forces and moments necessary for optimum power distribution within a propulsion system composed of azimuth propellers (rotative ones). To allocate thrusts the unconstrained optimization method making it possible to obtain a minimum-norm solution, was applied. A method was presented for assessing propulsion system capability to generate propulsive forces (set control inputs). For the case of lack of such capability an algorithm was proposed making modification of their values and determination of feasible propulsive forces (i.e. permissible control inputs), possible. A numerical example which confirmed correctness and effectiveness of the proposed approach, was also attached.

Opis:: Self-propelled wheelchairs favour the rehabilitation process, forcing the user to be physically active. Unfortunately, in most cases, the manual propulsion is not adapted to the individual needs and physical capabilities of the user. This paper presents the results of operational tests of a wheelchair equipped with a hybrid propulsion system in which the muscle strength generated by the user is assisted by two independent electric motors. The research aimed to investigate the influence of the applied control algorithm and the assistance factor (W) on the value of the muscular effort (MA) while propelling the wheelchair with the use of push rims. A modified ARmedical AR-405 wheelchair equipped with two MagicPie 5 electric motors built into the wheelchair’s hubs with a power of 500 W was used in this research. The tests were carried out on a wheelchair test bench simulating the moment of resistance within the range of 8–11 Nm. Surface electromyography was employed for the measurement of MA, specifically, a four-channel Noraxon Mini DTS apparatus. The research was carried out on five patients from the group of C50 anthropometric dimensions. The effort was measured for four muscles: deltoid–anterior part, deltoid–posteriori part, and triceps brachii and extensor carpi radialis longus. The effectiveness of the hybrid propulsion system was observed based on the extensor carpi radialis longus muscle. In this case, for the standard wheelchair, the MA ranged from 93% to 123%. In contrast, for a wheelchair equipped with the hybrid propulsion system, at W = 70%, the MA was within the range of 43%–75%.

Opis:: In order to meet the operation requirements of the beam supply with multi-working conditions, multi-modes and high efficiency, a dual-mode hybrid output control method combining phase-shifting and pulse-width dual-mode modulation technology with secondary side series-parallel operation is proposed. In this paper, the structure and working mode of the new dual full-bridge topology are firstly analyzed. Secondly, the main circuit parameters are designed according to the power performance indicators, and the losses under two control modes of phase shift and pulse width are calculated. Finally, comparing the losses of these two control methods, and combining the series-parallel operation mode of the secondary side of the transformer, a dual-mode switching control method of the beam supply is designed. In order to verify the rationality of the dual-mode mixed output control method, a principle prototype with a rated capacity of 2 kW, a rated voltage of 1 800 V and a switching frequency of 50 kHz was used for verification. Experiments show the effectiveness and superiority of the dual-mode hybrid output control method.

Opis:: The following paper presents load analysis of propulsion engine during ship's speed acceleration. This process is carried out after manoeuvring in order to receive, as fast as possible, exploitation speeds of the ship, achieved during the voyage. The analysis concerns direct propulsion power system of low-speed engine of constant pitch propeller. Wrong steering process of engine load changes in temporary states, can cause engine overloading, as the result of its operation on the external limiting characteristic and can end up in engine seizure. Control of engine operation is carried on through selecting of adequate setting of rotational speed governor, which for specified external conditions can result in adequate position of fuel link and the choice of adequate fuel index arm dose. Equalization of the power delivered by the engine in given conditions of work with power required by the ship’s propeller cooperating with the hull, will establish adequate rotational speed of the engine and finally the speed of the vessel. In order to speed up the sip's motion, there must occur an overflow of propeller thrust over the required thrust (resistance) and this, in turn, is connected with the necessity to ensure the engine power surplus over the power required for a given range of operation or in other words sailing speed. This article presents the working model of ship propelling system during speed acceleration and concerns mainly nonoverload running of the engine. The model described above has been verified during tests in real conditions at sea.
