Abstract: A constrained multivariable Generalised Predictive Control (GPC), which is based upon the T-S fuzzy model, is proposed for a class of non-linear systems. The proposed method can deal with the case of rate and amplitude constraints for the control signal with a way different from the classical constrained multivariable GPC, so the computation burden cut down with a degree and the control scheme can be used in the high speed sampled control systems. The simulation results demonstrate the effectiveness of the proposed algorithm.

Keywords: multivariable nonlinear systems; generalised predictive control; GT-S fuzzy models; constrained multivariable GPC; simulation; fuzzy logic.
