摘要

Abstract

Control performance monitoring has attracted great attention in both academia and industry over the past two decades. However

most research efforts have been devoted to the performance monitoring of linear control systems

without considering the pervasive nonlinearities (e.g. valve stiction) present inmost industrial control systems. In thiswork

a novel probability distribution distance based index is proposed tomonitor the performance of non-linear control systems. The proposedmethod uses Hellinger distance to evaluate change of control system performance. Several simulation examples are given to illustrate the effectiveness of the proposed method.
