摘要
舵机系统是导弹系统的重要组成部分,其性能的优劣直接影响整个导弹系统的性能。提出一种基于Liapunov稳定性理论、传统控制和自适应控制相结合的导弹电动舵机复合控制方法,充分结合经典控制器结构简单、稳定性能好、可靠性高和自适应控制抗干扰能力强的优点。利用Matlab/Simulink进行建模仿真。仿真结果表明:该控制方法能够有效地克服导弹飞行过程中舵机参数变化对系统性能的影响,具有较强的鲁棒性。
Servo-actuator system is an important part of missile system, and its performance will have great influence on performance of the whole missile system. A new kind of self adaptive control method of missile electric-servo-actuator, which is based on the Liapunov stability theory and characterized by the combination of traditional control and self adaptive control, is discussed and simulated. This method adequately integrates the strongpoint of traditional control and self adaptive control. Simulation results indicate that this method can effectively overcome the problem of the great influence of parameter change on the total missile system performance and is suitable for complicated flight environments.
