Dead-time Compensator Volterra Predictive Controller of a Van de Vusse CSTR

Abstract

This paper presents the application of a Dead-time Compensator Volterra-based Predictive Control (DTCVPC) to the benchmark control problem of the isothermal operation of a continuous stirred tank reactor (CSTR) with Van de Vusse reactions which includes an on-line concentration analyser that introduces a dead time on the process. The proposed controller incorporates a special dead-time compensator structure which allows for robustness improvement with respect to traditional nonlinear MPC in the presence nonlinearities, dead time and dead-time uncertainties. The use of the Volterra models in the optimisation allows for a low cost consuming algorithm.
