计算机的计算延时对二次型性能指标的影响

The Effect of Computation Delay on Quadratic Performance Index

本文针对具有计算延时的计算机控制系统,首先求出离散的闭环状态方程,然后将指标函数及其导数化为闭环状态的二次型函数,最后通过求解李雅普诺夫方程解出它们,从而可分析计算延时对系统性能的影响。

The effect of computation delay is considered in computer controlled systems. The discrete closed-loop state equations arc first derived. The performance function and its derivative with respect to the delay are then expressed by the closed-loop states and finally computed by solving Lyapunov equations.
