摘要
This study proposes a maximum power tracking (MPT) controller based on chaos synchronisation (CS) for a wind-energy-conversion system. The output power conversion of a wind generator depends on the wind speed, and therefore the optimal conversion of wind energy can be obtained by a variable-speed variable-frequency model. Based on a sensorless controller, CS can express dynamic behaviours by using an incremental conductance to adjust the terminal voltage to the maximum power point. A voltage detector based on the Sprott system is used to track the desired voltage and to control the duty cycle of a boost converter. For a permanent-magnet synchronous generator, the simulation results demonstrate the effectiveness of the proposed MPT controller.
