模糊PID控制在导弹姿态控制中的应用

Application of the Fuzzy-PID Control in the Missile Pose Attitude

导弹在飞行过程中,其飞行参数随着飞行条件的变化而发生较大变化,呈现严重的非线性,给控制系统的设计带来较大困难。结合模糊控制和PID控制的特点,提出一种基于模糊PID的控制系统设计新方法,然后在此基础上设计了俯仰通道的的自动驾驶仪,仿真结果表明这种控制器可使系统获得很好的稳定性和鲁棒特性。

A very severe nonlinear is presented because flight parameters vary along with the flight condition in the flight of missile which brings much difficulty to the design of control system. A new design method using fuzzyPID control combined with the advantage of fuzzy control and PID control is presented,and thoughts are proposed for the missile autopilot design. Simulation results show that a good robusticity as well as stability is acquired.
