Conclusion
In this study, a class of 2-D piecewise Lyapunov functions are constructed, together with a descriptor system approach, based on which a novel design method for 2-D PWA SOF controllers is proposed for uncertain Roesser-type continuous-time 2-D PWA systems. It is shown that with the proposed less-conservative control method the closed loop system achieves asymptotic stability with optimal \({{\cal H}_\infty }\) performance γmin. Simulation studies (shown in Appendix D) are given to show the effectiveness and less conservativeness of the proposed controller design results.
