在外扰时线性非时变系统的状态空间描述

The State-space Formulation for Linear Time-invariant System Influenced by External Disturbances

在外部干扰作用下,线性非时变系统仍需要求保持闭环系统稳定性,还能达到无差调节,从而需要设计"调节器"。在设计中,必须列写"外扰时的线性非时变系统的状态空间方程",在方程中要考虑干扰的作用的影响。以"双水槽系统的调节问题"作为示例,导出"调节器设计的状态方程",从而达到保持闭环系统稳定和无差调节的设计目标。

Influenced by the external disturbance,the linear time-invariant system must keep the stability of closed-loop systerm.and the ability to perform non-deviation regulation;we should design ＂regulator＂.the state-space formulation for linear time-invariant system is the first fundamental work in the design of regulator.It is necessary for design to consider the influence of external disturbance.This paper take two-water-vessels regulation problem as an example,the state-space formulation is derived.
