Controller Design for Diagonal Decoupling and Integral Action

A. N. Gundes

In the standard linear, time-invariant feedback system, controllers that achieve diagonal decoupling and closed-loop stability exist if and only if the plant satisfies the diagonal denominator condition or has no coinciding poles and zeros in the region of instability. A simple and systematic decoupling design procedure is presented under each of these conditions. The closed-loop poles can be placed at any desired points, and free parameters are included for satisfying additional design objectives. The designs are also extended to provide integral action in order to track step inputs with zero steady-state error.

对角解耦和积分作用的控制器设计

在标准的线性,时不变的反馈系统中,当且仅当工厂满足对角分母条件或在不稳定区域中没有一致的极点和零点时,才存在实现对角线解耦和闭环稳定性的控制器。在这些条件中的每一种下,提出了一种简单而系统的去耦设计程序。闭环极点可以放置在任何期望的位置,并且包含自由参数以满足额外的设计目标。设计也进行了扩展,以提供积分作用,以跟踪具有零稳态误差的阶跃输入。
