摘要
本文对一类多变量系统给出了一种广义最小方差自校正控制器,并讨论了系统加入这种控制器后的闭环特性,将二次型性能指标的加权阵与系统闭环极-零点联系起来,从而就可根据系统的期望闭环极点的位置在线选取加权阵。仿真结果表明这种控制器性能良好,工作可靠。
This paper presents a generalized minimum vatiance self-tuning controller for a class of multivariable systems. The closed-loop properties are discussed. The weighting matrices of a quadratic performance index are related to the closed-loop pole-zeroes so that the weighting matrices can be selected on-line according to the locations of the desired closed-loop poles. Simulation results illustrate the good performace and reliability of the controller.
