Simulation of sliding-mode control of wind energy conversion system of permanent magnet synchronous generator

In view of problem of bad stability of wind energy conversion system based on linear constant controller caused by stochastic volatility of wind speed, the paper proposed a design scheme of wind energy conversion system of permanent magnet synchronous generator based on sliding-mode control. It analyzed building principle of model of wind turbine, model of driving device and model of permanent magnet synchronous generator in the system , and introduced implementation of sliding-mode control strategy. The simulation result shows that the system has good speed tracking characteristic to realize maximum wind energy capturing.
