Comparative Study of SMC and PI Control of a Permanent Magnet Synchronous Generator Decoupled by Singular Perturbations

Abstract

This work presents a comparative analysis between the dynamic behavior of the synchronous generator with permanent magnets during a regulation of speed by regulators (PI) and regulators based on classical sliding mode of order one. In the first place, the vector control makes it possible to have a dynamics close to that of the DC machine, in other words, an asymptotically linear and decoupled dynamic. Then, the sliding mode control (SMC) to ensure good system performance and robustness against external disturbances and parametric variations. The systems performances were simulated and compared using Matlab/Simulink environment. Simulation results show the effectiveness of the proposed control strategies comparatively to the PI one.
