一类非最小相位对象解耦控制的非对消设计

Non-cancellation Decoupling Control Design Method of Non-minimum Phase Objects

本文分析了将基于零、极对消原则的前馈解耦设计方法应用于含有S右半平面零点的一类非最小相位对象时所存在的问题，提出了非对消解耦设计方法应用于该类对象的原理、特点及步骤，结合实例给出了仿真结果，所得结论对实际系统具有一定的指导意义。

This paper analyses the problems of feed forward decoupling control design method based on zero-pole cancellation for controling non-minimum phase objects which possess zeros located on the right half side of the S plane. The principles, characteristics and designing procedures based on the non-cancellation decoupling design method are proposed.Simulation results of a two inputs and two outputs coupled object are also given. The conclu sions obtained by this paper would provide some useful suggestions for practical systems.
