摘　　要：以飞行仿真转台伺服系统为研究对象,设计了一种带比例因子的模糊自适应PID控制器,通过误差和误差变化率在线模糊推理并调整比例因子和PID控制器的修正值。通过引入积分分离控制方法,在保证系统动态性能的前提下,一定程度上克服了模糊控制方法无法消除静差的缺点,也满足转台控制的实时性要求。仿真实验结果表明,该方法与传统PID控制相比,能够有效提高转台伺服系统的动态性能和鲁棒稳定性。A fuzzy adaptive PID controller with scale factor was designed for flight simulator servo system, which could fuzzy reason and tune the scale factor and modify parameters of PID controller online through the error and error change rate. By bringing in integral separation control method, it overcomes the fuzzy control method＇s disability on eliminating static error to some extent and ensures the dynamic performance of the servo system. The method also satisfies the requirement of real-time control of flight simulator. The consequence of simulation indicates that compared with the traditional PID control, the method modifies the ctynamic performance and robustness of flight simulator servo system.
