基于模型预测策略的波浪发电无速度传感器滑模控制
Speed sensorless sliding mode control of wave power generation based on model predictive strategy
摘要
Abstract
In order to improve the efficiency of direct-drive wave power generation system in complex sea conditions and reduce equipment maintenance costs,a speed sensorless sliding mode control scheme based on model predic-tion strategy was proposed.Taking the instantaneous power of the generator as the cost function,the optimal elec-tromagnetic force was solved and converted into the reference current.Through vector control and model predictive current control,the current was tracked to capture the maximum power of wave system.The speed direction was judged according to the reference current,and a sliding mode speed observer was designed to realize speed sensor-less control.The simulation results show that the system can operate within the safety constraint range by model predictive control strategy,the output power is improved,and the observation accuracy of sliding mode observer keeps high,which can enhance the robustness and safety of the system.关键词
