摘要
This article considers the non-weighted L-2 gain and asynchronous H-infinity control issues for continuous-time switched nonlinear systems. Firstly, Takagi-Sugeno (T-S) fuzzy models are employed to describe the nonlinear subsystems. By taking full advantage of the asynchronous features, a novel time-varying fuzzy Lyapunov function (TVFLF) and the corresponding controllers are all constructed separately in synchronous and asynchronous intervals. Based on the TVFLF approach, sufficient conditions of asynchronous H-infinity controller are established. Finally, two simulation examples are discussed to certify the effectiveness of the proposed results. (C) 2020 ISA. Published by Elsevier Ltd. All rights reserved.
