Feedforward plus feedback control scheme and computational optimization analysis for integrating process

Abstract

Integrating process is applied to many industries however there are very few research done on it. Determining PID settings for the closed-loop control of integrating process is a challenging task due to its inherent characteristic, which is only stable at one equilibrium operating point. This paper highlighted First Order plus Dead Time in representing process and disturbance model. Improvement of relative performance for transient and steady state response is achieved by using feedforward plus feedback control scheme. Moreover, computational optimization analysis was presented for developing a systematic way to design PID controller for the optimal performance of both servo and regulatory control problems. Performance of the controlled process were then compared in term of graphs, performance index and performance indicator. It is proven and concluded that designed PID controller settings by using computational optimization analysis eventually gives the best performance compared to other tuning methods for a Pumped-tank function of LOOP-PRO simulation software.
