Extended Predictive Controller for a First Order Process with Dead Time Model

Predictive control technique is a dominant technique to design a controller which is robust in nature. Predictive control techniques evolved from the dynamic matrix control concepts. The overshoot with the Process Variable (PV) around the set point has been observed as the limitation of Dynamic Matrix Control (DMC) algorithm. To overcome this drawback, few modifications were made in the dynamic matrix control algorithm by adding an extension. The extension is in the form of weighting matrix which will be used in the final control law. The results obtained with the extended DMC shows a significant difference in time domain analysis for both the primitive dynamic matrix control and the extended dynamic matrix control. The control algorithms developed were implemented on the First Order Plus Dead Time (FOPDT) model in Simulink platform with MATLAB 2015 environment
