Control systems of a non-stationary plant based on mpc and pid type fuzzy logic controller

Currently in the industry, at any stage of production process there is a high level of automation. As a rule, the majority of technological processes, occurring today in the industry, are non-stationary control objects. In order to improve the efficiency of automatic control system of non-stationary control object, researchers around the world, doing research, trying to combine the standard PID regulator with fuzzy adaptive controller. As a rule, setting a fuzzy controller is made based on the Mamdani controller. Also, recently, for the control of non-stationary control object are widely used controllers on the basis of a predictive model. The purpose of this paper is the comparative analysis of automatic control systems with PID regulator based on fuzzy logic and regulator on the basis of a predictive model (MPC-controller). In the course of research, stepwise disturbance of a certain amplitude and duration were applied to the control object. As a result, transient processes were obtained and quality indicators were determined. By comparing and analyzing the results obtained, a conclusion was made about the advantages of one controller over another.
