Model Predictive Controller Based on Laguerre Function for Binary Distillation Column

A performance improved Model Predictive Control for binary distillation column is proposed in this work. A MPC is designed to provide a timely control action ensuring optimum performance from the controller. Predictive control is now one of the most widely used advanced control methods in industry, especially in the control of processes that are constrained, multivariable and uncertain. In MPC, at each control interval an MPC algorithm attempts to optimize future plant behaviour by computing a sequence of future manipulated variable adjustments. The improvement in performance here we consider is the design of the MPC using Laguerre function, a discrete orthonormal basis function. It will help us in reformulating the predictive control problem and simplifying the solutions, in addition to tuning the predictive control system.
