Sažetak
PieceWise Affine (PWA) models comprise several affine dynamics defined over polyhedral regions in the regressor (state+input) space. In this paper we extend the clustering-based procedure for the identification of a PieceWise AutoRegressive eXogenous (PWARX) model proposed in [1]. By exploiting a priori process knowledge we choose an appropriate linear transformation of the regression vector for a better and more efficient identification of the process nonlinearities. Moreover, the computational complexity of the classification algorithm for finding the complete polyhedral partition of the model domain is significantly reduced. This modified clustering-based procedure is used to identify a PWARX model of the electronic throttle - a highly nonlinear and hard to control vehicle’ s component that regulates air inflow to the engine. Such a PWA model can then be used as a starting point for the controller synthesis.
