基于Matlab的模糊自适应PID控制器仿真研究 传统PID在对象变化时，控制器的参数难以自动调整。将模糊控制与PID控制结合，利用模糊推理方法实现对PID参数的在线自整定。使控制器具有较好的自适应性。使用MATLAB对系统进行仿真，结果表明系统的动态性能得到了提高。(Fuzzy adaptive PID controller based on Matlab simulation Traditional PID object changes, the controller parameters are difficult to be adjusted automatically. Fuzzy control and PID control to achieve PID parameters online self-tuning fuzzy inference method. Controller has better adaptability. Using MATLAB system simulation results show that the dynamic performance of the system have )
