— The structures and parameters of a sliding mode controller are required to change with the operating conditions and external disturbances in order to obtain satisfactory control performances in the global operation range. To solve this problem, a novel current sliding mode control (SMC) method with gain-scheduled parameters is proposed for permanent magnet synchronous machines (PMSM) in this paper. On the basis of the construction of the current sliding mode controller, the boundary layers of the switching gains are adjusted on-line with an adaptive method, and the controller coefficients the switching gains and the sliding surfaces are gain-scheduled in real time within the allowed boundary layers with the sliding surfaces as scheduling variables. The designed method not only ensures the system robustness, but also alleviates the system chattering and improves the control performances.
