Abstract :
Aimed at nonlinear MIMO system, a model predictive control (MPC) strategy based on least squares support vector machine (LSSVM) and mutative scale chaos optimization is proposed. Existent method doesn´t consider the constrain of control law and results in some meaningless solution. So the proposed method utilizes mutative scale chaos optimization technique to search control law in the feasible interval. The simulation results show that the method proposed has better control performance than MPC based on neural network.
