摘　　要：常规PID控制器参数设定之后,运行环境改变时不能实现参数的在线整定,这样会影响系统的控制效果.本设计以误差e和误差变化率ec作为输入,经过一定的模糊推理规则,对PID控制器的参数进行自动整定.在Matlab环境下对系统进行了仿真,从仿真的结果可以看出,添加模糊控制环节后,系统的动静态性能得到了提高.同时基于ARM7处理器完成了该控制器的软硬件设计.When operating environment changed,the traditional PID controller can＇t online regulate its parameters, which are configured well at the beginning. And that would affect control performance of system. Taking error and decay rate of error as inputs in the design,arguments of PID controller can reach self - tuning function, as to some accurate fuzzy sets. From the result of simu- lation done with Matlab, dynamic and static performances of system added fuzzy controller are im- proved. The author also completed the hardware and software design of the controller based on ARM7 processor.
