Abstract :
The authors consider the speed controller design problem for a permanent magnet synchronous motor (PMSM). Based on the Takagi-Sugeno fuzzy approach the authors design a fuzzy speed controller as well as a fuzzy load torque observer. The authors derive sufficient conditions for the existence of the controller and the observer in terms of linear matrix inequalities (LMIs). The authors give LMI parameterisations of the gain matrices. The authors also derive LMI conditions for the existence of the fuzzy speed controller and the fuzzy load torque observer guaranteeing --stability, quadratic performance and H2/H performance. The authors implement the proposed load torque observer-based fuzzy speed control system by using a TMS320F28335 floating point DSP, and give simulation and experimental results to show the effectiveness of the proposed method.
