基于工程整定法的模糊PID

A FUZZY PID CONTROLLER BASED ON ENGINEERING TURNING METHODS

  • 摘要: 在PID工程整定法的基础上,提出一种基于模糊规则的模糊PID复合控制算法.算法首先根据扩充临界比例法等工程PID整定方法将PID公式简化,然后通过模糊控制规则和模糊推理确定一张模糊控制表,在时实控制中通过对模糊控制表的查询,在线调节PID控制参数.液压电梯的实验和仿真结果表明,本文提出的控制控制算法具有算法简单、控制品质优良等特点.

     

    Abstract: A new fuzzy PID control algorithm based on PID engineering turning methods is proposed in this paper. The designing method of the algorithm can be divided into two steps: firstly, simplify PID formula using Z-N or critical proportion methods, then construct a fuzzy control table by fuzzy reasoning. During real time control, the parameter of PID controller can be adjusted by looking up the fuzzy table. Experimental and simulation results in hydraulic elevator show that the algorithm proposed has good performances.
