A Design Method of Strong Stability Self-Tuning Controller Based on On-Demand Type Feedback Control

Abstract

This paper proposes a design method of strong stability self-tuning controller based on on-demand type feedback control. For safety in industrial applications, although it is important to consider on-demand type feedback control system, the previous papers about on-demand type feedback control did not consider the influence of noise and fixed the design parameter to constant value. Therefore, this paper extends the design parameter of on-demand type feedback control as stable rational function through the design method of strong stability system using coprime factorization. Moreover the self-tuning controller of the proposed method is given and the control result with noise is shown by numerical example.
