Abstract :
Control of electric actuator using brushless DC motors for tactical missiles is introduced in this paper. The electric actuator is a key part of the flight control system. A new kind of PD controller is implemented which is different from the traditional ones. The proportion reacts immediately to the error. And the differentiation function works on the feedback of the system in order to predict the future output and restrain the overshoot. The simulation and experiment results verify its excellent dynamic and static performances. Finally the test methods for evaluating the dynamic and static characteristics are provided.
