【摘要】 针对经典PID控制器仅能在离线状态进行参数自整定的问题,在PID控制和模糊控制的基础上,设计了用于步进式加热炉温度控制系统的模糊自整定PID控制器。并用MATLAB进行仿真研究,与经典PID温度控制系统相比,此种控制器能迅速消除系统余差,同时具有PID控制器高精度的特点,又具有模糊控制器适应性强、反应迅速的优点。从而保证了此PID控制器具有预期的动静态特性。更多还原

【Abstract】 Aiming at the problem that conventional PID controller can not adjust parameters itself on line,a method of PID-control with fuzzy self-adjusting parameter is proposed based on fuzzy control technique.The result of simulation in fuzzy logic tool box of MATLAB proves that the controller can e-laminate steady state error of system and improves the performance of ordinary fuzzy controller.It possesses both the precise character of PID controller and the flexible advantage of fuzzy controller,and can guarantee that the regulation system has good dynamic and static quality.更多还原
