摘要
以参数大范围变化的导弹为研究对象,分别设计PID控制器和模糊控制器,并对PID控制器和模糊控制器组成的稳定回路进行仿真,仿真结果表明,PID控制器不能适应参数大范围的变化,表现为容易产生超调。简单模糊控制器对外界参数具有较好的适应性和鲁棒性,但存在稳态误差,通过采取模糊——积分并联混合,改善了模糊控制的稳态性能,提高了模糊控制的稳态精度。
In this paper,the PID controller and the fuzzy logic controller are designed for the guided missile with the parameter changing in a big scope, and the control system is simulated by MATLAB. Numerical simulation results show that PID controller is not applicable when parameters changed in big scope ,which make overshoot ,and the simple fuzzy logic controller has better adaptability and robustness, but it has steady state error. The fuzzy-integral connect in parallel controller is designed for improving steady-state performance and steady-state accuracy.
