永磁直驱风电系统MPPT模糊改进线性自抗扰控制
MPPT control with fuzzy improved LADRC for permanent magnet direct drive wind power system
针对永磁直驱风电系统的非线性、易受到外部扰动影响等问题，提出了一种最大功率跟踪的模糊改进线性自抗扰控制（fuzzy improved linear active disturbance rejection control, fuzzy-ILADRC）方法。采用各状态变量与其观测值之间的误差设计了改进线性扩张状态观测器，并分析了其收敛性，表明改进线性自抗扰控制能够提升系统的响应速度和观测精度。结合模糊控制对改进线性自抗扰控制器的参数进行在线寻优，使其具备一定的参数自整定能力。仿真结果表明，在不同风速作用时，相比于传统PI和LADRC控制方法，Fuzzy-ILADRC控制方法转速跟踪的速度更快、控制精度更高且无超调现象，能够更好地实现风能的最大功率跟踪，抗扰能力强、鲁棒性好。
英文摘要:
A fuzzy improved linear active disturbance rejection control (Fuzzy-ILADRC) method for maximum power point tracking is proposed to address the problems of nonlinearity and susceptibility to external disturbances in permanent magnet direct drive wind power systems. An improved linear extended state observer is designed using the error between each state variable and its observed value, and its convergence is analyzed, indicating that the improved linear active disturbance rejection control can improve the response speed and observation accuracy of the system. Online optimization of the parameters of an improved linear active disturbance rejection controller is conducted incorporating fuzzy control, so as to make it have certain parameter self-tuning ability. The simulation results show that the Fuzzy-ILADRC control method has faster speed tracking, higher control accuracy, and no overshooting phenomenon than the traditional PI and LADRC control methods under different wind speed conditions, which can better realize the maximum power point tracking of the wind energy, with strong disturbance rejection capability and good robustness.
