在外扰时纯增益调节器的设计问题

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的稳定性,而且还能达到输出调节,从而需要设计调节器。首先给出两个基本引理,导出判别这个系统达到上述要求的条件及计算方法。如果系统状态和外扰状态均可直接测量时,即可作"纯增益调节器"的设计,此调节器即可达到渐近稳定,且有满意的动态特性,还可使系统满足无差调节(即系统输出不受外扰的影响)。

Net-gain Regulator's Design Problem on External Disturbances

Influenced by the external disturbance,the linear invariant system must keep the stability of closed-loop system and the ability to perform output regulation,so to design the ＂regulation＂.This paper firstly introduce two fundamental lemmas,then explain the criteria and the design-method of the system which should satisfy the above-mentioned regulator＇s requirement.If all information of the system-state and the external-state may be measured directly,we can design ＂net-gain regulator＂,the ＂regulator＂ should has the features as follows：the stability of the system is the attained,and have the excellent dynamic behavior,and non-deviation regulation（namely,the system begin not influenced by external disturbance）.
