报告题目:Adaptive fractional fuzzy integral sliding mode control for PMSM model

内容简介:This lecture aims to address the stabilization problem of permanent magnet synchronous motor (PMSM) based wind energy conversion system (WECS) through a novel adaptive fractional fuzzy integral sliding mode control (FFISMC) scheme in contrast to the traditional integer order control schemes. The main objective of modeling the fractional order control for nonlinear PMSM is to enhance the convergence rate which is effectively better when compared to integer order control schemes. In this regard, firstly, the nonlinear PMSM model is transformed into equivalent linear sub-models through an effective Takagi-Sugeno (T-S) fuzzy membership rules. Then, a novel automated (adaptive) controller is designed along with fractional sliding surface which involves an integral term to control the considered PMSM. In general, adaptive controllers are much more effective than manual controllers. Further, the sufficient conditions are derived in terms of linear matrix inequalities via constructing the novel fractional fuzzy Lyapunov functional with quadratic terms, which guarantees the global stabilization of PMSM-based WECS. Overall performance and effectiveness of the proposed theoretical results are demonstrated through numerical simulations.
