摘　　要：基于Lyapunov稳定性理论,提出了导弹电动舵机的一种自适应控制算法。以Lyapunov稳定性判据为前提,保证算法的稳定性。综合自适应控制算法与经典比例积分微分(PID)控制算法,给出了模型参考自适应控制(MRAC)与分离比例积分(PI)复合控制。仿真结果表明:由该控制算法可在考虑舵机铰链力矩等因素变化条件下,获得到良好的输出跟踪性能和鲁棒性。An adaptive control algorithm based on Lyapunov stability theory was put forward for missile-servo-actuator in this paper.This algorithm was stable by using Lyapunov stability criterion.Integrated with classical PID control algorithm,model reference adoptive control（MRAC） and detaching PI compound control was formed.The simulation results showed that the proposed method output tracking was valid and robust when the hinge moment was changed.
