Testo completoThe present work deals with the development of limited motion actuators dedicated to the air flow regulation of internal combustion engines. Because of the recent European Standard applied to car manufacturers, new conceptions of internal combustion engines need a new air flow management such as the low pressure exhaust gas recirculation. According to a state of art on electromechanical actuators that manage the combustive flow, there are mainly two electric topologies for rotary movements: the first one is an indirect drive which is composed of a brushed DC motor associated with a reduction spur gear set, the second one is a direct drive with a brushless DC motor. The topologic analysis carried out in order to design these actuators is based on a multi-physics approach involving mechanical, electrical, magnetic, thermal behaviours and control laws. With requirements, four magnetic topologies have been modelized in linear behaviour and optimized to minimize the external volume. Each actuator is composed of two bipolar permanent magnets on the rotor and two polar teeth on the magnetic core. With an attractive criteria per volume unit torque for a limited stroke application, one of them is chosen to minimize the electrical energy consumption. In order to compare the results of this optimized actuator, a brushed motor and a two reduction stage gear set are modelized and optimized with the aim of minimizing the energy consumption with the same required performances. This approach associates physical and dynamical constraints on actuator designs and contributes to realize a global optimization of machine, power electronics and control law

Testo completoA trajectory planning method for flatness-based control of PMSM drives for EV water pump application is proposed in this thesis. This approach is primarily intended to ensure PMSM motor current remains within permissible limits through indirect flatness-based control while still having the advantages of one-loop control. Furthermore, the constraint on switching voltage has been taken into account in the proposed trajectory planning method to maintain the proper operation of the PMSM drive system in steady-state mode as well as during transients. A window-based trajectory planning function is used for the PMSM drive in this method. The trajectory function is generated using an optimization algorithm considering the speed overshoot, motor current, and switching voltage constraints. Unlike conventional trajectory planning, which is a second-order function, this method takes controller limits into account while using one-loop flatness-based control
