Abstract:

This paper discusses neural multi-models based on Multi Layer Perceptron (MLP) networks and a computationally efficientnonlinear Model Predictive Control (MPC) algorithm which uses such models. Thanks to the nature of the model itcalculates future predictions without using previous predictions. This means that, unlike the classical Nonlinear Auto Regressive with eXternal input (NARX) model, the multi-model is not used recurrently in MPC, and the prediction error is not propagated. In order to avoid nonlinear optimisation, in the discussed suboptimal MPC algorithm the neural multi-model is linearised on-line and, as a result, the future control policy is found by solving of a quadratic programming problem.
