摘要
对非线性大滞后等特殊的系统,存在常规PID控制器控制效果不甚理想的问题,为此结合模糊控制和常规PID控制二者的优点提出了模糊PID(Fuzzy-PID)控制方法。首先建立模糊规则、进行模糊推理,确定PID控制器的参数,再由PID控制器直接控制对象,实现实时控制的目的。将所设计的模糊PID控制器应用于具有大时滞,对大惯性的皮革温度收缩测定仪温度控制系统检测其性能,计算机仿真试验结果表明:Fuzzy-PID控制器与常规PID控制器相比较,确实提高了仪器温度控制系统的自适应能力和鲁棒性,改善了系统的动态性能和静态性能,能使非线性、大滞后等特殊的系统达到了良好的控制效果。
It is difficult for general PID to control systems with nonlinear and large delay properties. Therefore, a Fuzzy - PID controller is proposed by combining the advantages of both the simple Fuzzy Control and traditional PID control. This control algorithm can be divided into two steps： building the fuzzy rules by simulation and analysis,obtaining the parameters of PID controller by reasoning; realizing real - time control by fuzzy - PID. And by computer simulation and comparison, it is concluded that the use of the method in the system can greatly improve the robustness and the dynamic＆static properties of the system.
