Further Improvements on the Problem of Optimal Fuzzy H-infinity Tracking Control Design for T-S Fuzzy Systems

摘要

In this study, further developments on the problem of optimal fuzzy H-infinity tracking control design for T-S fuzzy systems are considered. The controller has a parallel distributed compensation structure. The presented local control law has a suitable structure for tracking purposes. It consists of six parameters to lead to a more flexible and less conservative tracking performance. The parameters of the control law are found through the solution of a set of linear matrix inequalities (LMIs). Unlike the observer-based approaches, no particular assumptions are made in obtaining the required LMIs. The optimal controller can be also obtained through the solution of a convex optimization problem. On a benchmark example, a complete comparison is made with some existing results.
