Simultaneous Stabilization And Performance Design Of Frequency Domain Analysis

The article is based on the stable coprime factorization resulted in the parameterization result of simultaneously stabilizing controller, uses the Nyquist Stability Criterion and the internal model principle of eliminating system steady error, discusses the performance design problem of simultaneous stabilization. The article gives the design methods and steps of simultaneous stabilization H~ performance of a family of SISO stable minimum phase plants, 5150 system asymptotic tracking and disturbance attenuation, MIMO system asymptotic tracking and disturbance attenuation, MIMO system asymptotic tracking and static decoupling. Finally, the article illustrates the actual applicability and effectiveness of the design method by examples.
