摘要
系统非线性的存在 ,使之在不同工作点上系统特性差别很大 ,这对使用广义最小方差控制的加权自校正控制的控制效果带来很大影响。本文针对这一情况提出可变性能指标加权自适应控制 。
Because of the nonlinearity,the performance of system changes at different set_point.And the performance of generalized minimal variance self_tuning controller changes too.In this paper,a self_tuning controller with changeable performance cost is peoposed.Simulations of the control of PAg in light sensitive materials are presented.The result shows significant improvement of the strategy.
