多变量非方系统多环PI控制器设计
Multi-loop PI Controller Design for Multivariable Non-square Systems
摘要
Abstract
Based on the theory of equivalent transfer function (ETF),we propose a multi-loop PI (proportional in-tegral)controller design method for high dimensional multivariable non-square systems with time-delays. Firstly,by exploiting the relationship between the ETF and the generalized inverse of transfer function of the non-square systems,an analytical expression of ETF is derived.Then,based on the obtained ETF,the multi-loop PI controler parameters are calculated by exploiting IMC-PID (internal model control-proportional inte-gral derivation)theory with the help of the Maclaurin expansion.The proposed ETF design approach not only has higher accuracy,but is also applicable to high dimensional non-square systems.Finally,several examples are given to demonstrate the simplicity and the effectiveness of the designed method.关键词
