This paper aims to implement a new contribution for sliding mode control (SMC) of permanent magnet synchronous generator (PMSG) for wind systems conversion with track the maximum power point tracking (MPPT) power. The SMC is a very popular approach due to its robustness in dealing with the non-linear electrical power systems. In this work, the application of the SMC control is by using the non lineare model of the PMSG. The objective of this work is to control stator active and stator reactive power, and the voltage-frequency for a better injection into the network. The results obtained show better robustness.
In this work, we are developing a new control strategy for wind systems based on the permanent magnet synchronous generator (PMSG). The SMC sliding mode technique is based on the principle of Lyapunov stability in order to make a nonlinear system close to linearity. the use of such a technique with an improvement in regulators to suppress the Chattering phenomenon shows a great improvement in the performance of wind systems. The performance and robustness of the PMSG and the wind turbine are analyzed and compared by simulation based on Matlab / Simulink.
