Abstract :
A novel approach of multivariable fuzzy predictive functional control is presented. The control law is derived in the state-space domain, and given in an analytical form. The method was tested on a model of a 2-by-2 MIMO nonlinear plant, and compared to the control system using gain-scheduling of a linear dynamic compensator. The process was linearized in 63 operating points, and the compensator parameters were optimized using Edmunds´ frequency-response-based technique. The results show that the proposed approach exhibits better reference-model tracking in a wider operating range, even without the use of optimization
