摘要:

提出一种新的极点配置广义预测控制方法,该方法在性能指标函数中引入控制增量的当前及过去值项来进行闭环系统极点配置,同时通过调节控制器中的设计参数可改进闭环系统动态性能,且能保证闭环系统无稳态输出误差。

关键词: 广义预测控制, 极点配置, 稳态误差

Abstract:

This paper proposes a new pole assignment approach for generalized predictive control. In this approach, the present and past values of the control increment are introduced into the cost function to assign the closed-loop poles, meanwhile, by tuning the design parameter of the controller, the dynamic characteristics of the closed-loop system can be improved, and the steady state output error is eliminated.

Key words: generalized predictive control, pole assignment, st eady state error
