Error bound analysis and optimal construction of non-parametric PWA models

This paper discusses non-parametric PWA models which are recently developed for modelling a broad class of nonlinear systems. First, as for the accuracy of such models, an upper bound of output errors between the original system and the PWA models is given. Then, a construction method of such models is proposed, which minimizes the error upper bound. Furthermore, simulation results are given to show the effectiveness of the proposed construction method.
