Operator based robust nonlinear control for Peltier actuated process by robust right coprime factorization and pre-compensator

摘要

In this paper, operator based robust nonlinear con-trol system design is considered for Peltier actuated process by using robust right coprime factorization and pre-compensator. A merit of the operator based approach is the simplicity of analyzing the stability of nonlinear systems. Especially, operator based robust right coprime factorization is one of the most useful methods to analyze and stabilize a nonlinear process. In details, operator based tracking scheme with pre-compensator is designed to control the Peltier actuated process. The effec-tiveness of the designed system is confirmed by experimental results.
