Abstract :
A new predictive control algorithm based on single neural network for a kind of MIMO nonlinear systems is presented. In the control process, only one RBF network is used to calculate the multi-step-ahead predictive outputs. To overcome the drawbacks of the traditional cost function, a new multi-step predictive cost function with differential part is constructed. This strategy can accelerate the process of receding horizon optimization and reduce the influence caused by model error, disturbance and uncertainty to the controller. Simulation and application show the effectiveness and great performance.
