| مستخلص: | Electro mechanical actuator (EMA) is an important type of power-by-wire (PBW) actuator. The dynamic performance of EMA is a key issue especially when it is mounted on a fighter aircraft. Generally, the EMA adopts permanent magnet synchronous motor (PMSM) as the drive unit. It is a position controlled cascade system with an inner current control loop. This study focuses on the current control loop and proposes a scheme which utilizes optimal current trajectory control to exploit the inherent torque capability of the motor. Compared with traditional current control, i.e. id=0 strategy, the torque capability of the motor is maximized and the speed range is expanded. This directly improves the EMA dynamic performance. Faster transient process is demonstrated experimentally, which verifies the efficiency of the proposed scheme. |
