摘要 为了更好地获取风能,构建了一种基于模型预测转矩自抗扰的最大功率追踪控制系统,用于直驱永磁同步发电机(permanent magnet synchronous generator,PMSG)来实现系统的最大输出功率追踪。为了提升PMSG响应性能,增强PMSG抗扰动性能,首先在电流环设计了模型预测转矩控制(model predictive torque control,MPTC),同时在速度环提出了一种参数补偿改进自抗扰控制(active disturbance rejection control,ADRC)策略,该方法继承了ADRC和MPTC的优点,可以很好地处理内部和外部干扰、建模误差和风速变化等不确定性问题,以实现在不同风速下最大功率追踪性能。从仿真结果可知当风速变化较小时所提控制策略转速静态误差几乎为0,传统MPTC控制策略误差为0.2 rad/s;当风速变化较大时所提控制策略转速静态误差较小,传统MPTC控制策略误差达到5 rad/s。研究结果表明所提出的控制方法在最大功率追踪较传统控制器具有更好的动态响应性能以及抗干扰性能。 In order to better obtain wind energy,this article constructs a maximum power tracking control system based on model predictive torque active disturbance rejection,which is used for direct-drive permanent magnet synchronous generator(PMSG)to achieve maximum output power tracking of the system.In order to improve the response performance of PMSG and enhance the anti-interference performance of the system,this article first designed model predictive torque control(MPTC)for the current loop,and proposed a parameter compensation improved active disturbance rejection control(ADRC)strategy for the speed loop.This method inherits the advantages of ADRC and MPTC,and could effectively handle uncertainties such as internal and external interference,modeling errors,and wind speed variations to achieve maximum power tracking performance at different wind speeds.From the simulation results,it can be seen that when the wind speed changes slightly,the static error of the proposed control strategy speed is almost zero,while the error of the traditional MPTC control strategy is 0.2 rad/s.When the wind speed changes significantly,the error is small,and the error of the traditional MPTC control strategy reaches 5rad/s.The research results show that the proposed control method has better dynamic response performance and anti-interference performance than traditional controllers in maximum power tracking.
