Pole-Zero Cancellation Method for Multi Input Multi Output (MIMO) Temperature Control in Heating Process System

Abstract

With the rapid development of industrial technology, the multi-point (multi-input multi-output) heating processing systems with integrated temperature control have been increasingly needed to achieve high-quality and high-performance processing. In this paper, in response to the demand for proper transient response and to provide more accurate temperature controls, a novel pole-zero cancelation method is proposed for multi-input multi-output (MIMO) temperature control in heating process systems. In the proposed method, the temperature differences and transient characteristics of all points can be improved by compensating dead time difference and coupling effect together by matrix compensation and pole-zero cancelation with the feedforward reference model. Both simulations and experiments were carried out. The results were compared to the well-tuned conventional PI control system and PI plus decoupling compensation system to evaluate the control efficiency of the proposed method.

“…In the paper authored by Xu et al [15], a pole-zero cancellation method was proposed for temperature control in heating process systems, where the temperature differences and transient properties of all points can be adjusted by implementing dead time difference compensation and pole-zero cancellation with the feedforward reference model. Compared with conventional control approaches, the control efficiency of the proposed approach was well-demonstrated.…”

Decoupling Adaptive Smith Prediction Model of Flatness Closed-Loop Control and Its Application

“…Decoupling control solves the coupling problem of the flatness control system, but does not solve the pure time-delay problem. The decoupled flatness control system can be regarded as three independent loops, and the predictive controller can be designed by solving single-loop pure time-delay; in this manner, the controller design is simplified and the practicability of the controller is enhanced [23,24]. Smith predictive control is an effective solution to the problem of single-loop pure time-delay.…”

Automatic Hybrid Attack Graph (AHAG) Generation for Complex Engineering Systems

“…A novel pole-zero cancelation method was proposed by [6] for Multi-Input Multi-Output (MIMO) temperature control in heating process systems. In the proposed method, the temperature differences and the transient response of each point can be controlled by considering the dead time and the coupling effect of the MIMO system.…”
