中文摘要: 为了提高传统风能最大功率点跟踪控制的鲁棒性,提出了新的滑模自适应最大功率点跟踪控制策略。由于实际无速度传感器的风电系统变量难以测量,为此构造了滑模状态观测器来估计系统的转速跟踪误差,并基于估计值设计了滑模自适应最大功率点跟踪控制器。最后,基于MATLAB/Simulink仿真平台搭建了完整的风电系统仿真模型。仿真结果表明,在不同风速扰动作用下,所提出的控制策略均能实现良好的跟踪和控制效果,提高了风电系统的鲁棒性,保证了风电系统的最大功率输出。
Abstract:A new Maximum Power Point Tracking control strategy based on sliding mode adaptive control is put forward to improve the robustness of traditional MPPT control in the wind power system.As the variable is difficult to measure in the wind power system without speed sensor,the sliding mode state observer is designed.The observer is used to estimate the rotating speed error and the sliding mode adaptive controller is constructed based on the observer value.In the end,the simulation model is built based on the MATLAB/Simulink platform.The simulation results show that the proposed control strategy can achieve good tracking and control effect under the different wind speed disturbance,improve the robustness of wind power system and ensure the maximum power output of wind power system.
