Control Strategies of Thrust Ripple Suppression for Electromagnetic Microgravity Facility
Electronics (Switzerland)This paper presents an innovative solution that is able to suppress the thrust ripple in a high-power asynchronous linear induction motor (LIM) used in a microgravity experiment facility electromagnetic launch (MEFEL) system. By addressing the crucial need for low levels of thrust ripple in MEFEL applications, we propose a dynamic model-based adaptive ...
