A Survey on Gain-Scheduled Control and Filtering for Parameter-Varying Systems

Abstract EN

This paper presents an overview of the recent developments in the gain-scheduled control and filtering problems for the parameter-varying systems.

First of all, we recall several important algorithms suitable for gain-scheduling method including gain-scheduled proportional-integral derivative (PID) control, H2, H∞ and mixed H2/H∞ gain-scheduling methods as well as fuzzy gain-scheduling techniques.

Secondly, various important parameter-varying system models are reviewed, for which gain-scheduled control and filtering issues are usually dealt with.

In particular, in view of the randomly occurring phenomena with time-varying probability distributions, some results of our recent work based on the probability-dependent gain-scheduling methods are reviewed.

Furthermore, some latest progress in this area is discussed.

Finally, conclusions are drawn and several potential future research directions are outlined.
