Sufficient and stable positioning torque is necessary for the parking of an electric vehicle driven by switched reluctance motor (SRM). Considering highly nonlinear characteristic SRM, control with high stability power consumption economy important issue. This paper presents optimized method SRM to achieve optimal simultaneously. The static torque-angle curve a four-phase 16/12 analyzed, based on which region position (presented rotor angle) obtained considering uncertainty conditions. To...

Multi-motor synchronous drive system is increasingly widely used in industry and manufacturing, where its control structure strategy affect the quality efficiency of production. In order to solve contradiction between fastness overshoot, difficulty determining compensation law conventional PID, cross-coupling control, master-slave strategies multi-motor this paper proposes a self-coupling PID based on ring adjacent reduce complexity structure. Furthermore, analyzes parameter tuning rules...

Wind turbines (WTs) are based on power electronic converters. Due to different control schemes of converters, WTs exhibit diverse external characteristics when grid symmetrical fault occurs. Thus, the output current and cannot be forecasted, which is a challenge for system stability. In this regard, paper proposes novel strategy Permanent Magnetic Synchronous Generator (PMSG) wind turbine systems. The aims force PMSG stable EFC during provide an reference system. Besides, proposed at...

Switched reluctance generator (SRG) has the advantages of rotor without winding and permanent magnet, so it is suitable for field high speed temperature. The traditional signal-step commutation method adjusting turn-on angle turn-off limited ability to achieve optimal adjustment. Because they interact with each other at constant power output. To improve bus voltage quality operational performance SRG speed, a two-step control adopted. adds zero-voltage freewheeling process between excitation...

The large vibration and noise of the switched reluctance motor (SRM) restrict its wide application in various industries. Compared with current chopper control, pulse width modulation (PWM) control will introduce high frequency harmonics fixed excitation force. Thus component is introduced into vibration.

Power converter topology is an important part of the switched reluctance motor drive, and it occupies proportion in performance cost entire SRD. The asymmetric half-bridge most common power topology, with strongest independence between phase windings, flexible chopping mode, simple control. 2(N+1) reduces switching tube on its basis, which can effectively reduce volume converter. However, at same time also each phase. Current freewheeling difficult demagnetization may increase difficulty...
