复杂给矿过程信号补偿法驱动的智能PI控制
Intelligent PI control driven by signal compensation method for complex ore feeding process
摘要
Abstract
Conventional PI control is difficult to ensure stable operation for the complex ore feeding process.Firstly,this article analyzes the complexity mechanism characteristics of the ore feeding process,and establishes a hybrid dynamic model consisting of a low order linear model and an unknown high-order nonlinear dynamic system.Secondly,an intelligent PI control method is proposed,which is composed of signal compensation method,rule inference control and switching mechanism.This method utilizes a one-step optimal control law to design a signal compensator,which weakens the influence of nonlinear disturbances and transmission delay on the ore feeding process,and combines rule inference to improve the closed-loop control effect.Regarding switching problem of the ore feeding machines,an intelligent switching mechanism has been designed to ensure the reasonable allocation of five ore feeding machines.Finally,the proposed method is applied to complex ore feeding process,the actual application results show that the proposed method can control the ore feeding amount and frequency within the target value range required by the process.关键词
