Adaptive predictive control of time-delay systems

Abstract

Design of an optimal controller for higher-order systems often leads to complex control algorithms. One of the possibilities of control of such processes is their approximation by a lower-order model with a time-delay (dead time). These time-delay processes can be effectively handled by model-based predictive control (MPC) method. The paper deals with design of an algorithm for adaptive predictive control of higher-order processes which are approximated by a second-order model of the process with a time-delay. The controller was tested and verified by simulation on experimental data from a laboratory model of a heat exchanger.
