Design of MFCS with Time-Delay for Chemical Processing System

Abstract

We can design model following control system (MFCS) with time-delay whose internal states are bounded. Time-delay widely exists among controlled objects in computer control processes, power systems, chemical processing systems, metallurgical processing systems, environmental systems and communication systems transmission systems and other industrial production activities[1]～[5], and makes it difficult to evaluate effects of control system input signals in time, which will ineluctably deteriorate performance of the control system in automatically removing outside disturbances, and influence stability of the system. This paper discusses a design of predictive control of MFCS for the linear time-delay based on the model following control theory proposed by Okubo[6], and is thus considered to be innovative and applicable. It is confirmed on basis of a numerical example that the output signal of the control system asymptotically follows the reference model signal in the case of the existence of disturbances.
