具有一对主导极点的最优调节器设计

Design of the Optimal Regulator with a Pair of Dominant Pole

本文分析了单输入线性定常可控系统开环特征多项式和最优闭环特征多项式与二次型指标中Q阵的关系,提出了一种具有一对期望主导极点的线性二次型最优调节器设计方法,该方法简单,计算容易,便于在实际工程设计中应用。

The relation among the open-loop characteristic polynomial for a single input linear con- stant controllable system and the optimal closed-coop characteristic polynomial and the weighting matrix Q in the quadratic performance index is analysed in this paper. a linear quadratic optimal reaulator with a pair of dominant pole is presented. The design method is simple and easy, so it can be used in practical engineering.
