Two Tank Level Control Systems Using Dynamic Matrix Control and Study of Its Tuning Parameter

Abstract

Liquid level has a major role in the process industries especially in chemical plants, pharmaceutical industries, etc and the controlling of this parameter is a big task. Every time controlling manually is not possible therefore by using simulation methods, these targets are achieved. This project deals with the Two Tank Systems on which Dynamic Matrix Controller algorithm has been applied for the simulation work. Effect of tuning parameters such as prediction horizon (p), control horizon (m) and model length (n) are studied and data were collected. Different performances i.e. rise time, settling time etc. were seen for different varying tuning parameters. Also the Empirical Formula has been derived, based on the observations for optimal performance of the system. Process parameters have been changed and best performance has been observed with respect to the time constant. This project work manages the study and examination of DMC for the given Tank System under MATLAB simulation window
