针对常规PID控制不具有自适应能力，对于时变、非线性系统控制效果不佳。提出了将模糊技术与PID控制相结合的控制方式，设计模糊控制器。(Conventional PID control with adaptive capabilities, time-varying, nonlinear system control ineffective. Fuzzy and PID control combined control mode fuzzy controller design.)

说明：  基于matlab的编程，信道仿真的，很好很强大(Matlab-based programming, channel simulation, very good very strong)

说明：  PSO MATLAB 程序，有助于求解混合非整数规划问题(PSO MATLAB )
