模糊PID双层参数整定及其在固化炉中的应用
Two-level tuning for fuzzy PID control and its application to curing oven
摘要
Abstract
A two-level tuning method for fuzzy PID(proportion integration differentiation) controller is proposed.It includes scale factor tuning and member function tuning.An analytical model of fuzzy PID controller is derived first,which consists of a linear item and a nonlinear compensation item.The nonlinear compensation item is considered as a process disturbance,fuzzy PID control is tuned with the linear item and the SOPDT (second-order plus dead-time) model of plant based on the gain margin.Then triangle member functions are tuned by PSO (particle swarm optimization) algorithm.Simulations show that the proposed method is effective.Finally,the method is applied to the temperature control process of curing oven to improve the temperature control effect.关键词
