摘　　要：现今流量控制系统很多都使用常规PID控制器,这样虽然比较方便,但不能在线整定参数,因而不能很好地控制非线性等复杂系统。在本系统中,采用模糊PID控制器来设计控制流量。模糊PID控制器将PID控制和模糊控制两种方法结合起来,既能消除稳态误差,又能对复杂系统进行简单有效的控制,从而达到控制要求。Nowadays, the conventional PID controller are more used in the flow control system, it is quite convenient, but cannot adjust parameter on line, thus cannot control non-linearly and so on complex system well. In this system, the fuzzy PID controller is used to design the control of current capacity. Fuzzily controller and the PID controller are unified in the fuzzy PID controller, both can eliminate the static error, and carry on the simple effective control to the complex system, thus meets the control requirements.
