摘要

摘要: 最优转矩法因其所需测量状态较少、易于实现的特点,被广泛应用于风力机的最大功率点跟踪(Maximum power point tracking, MPPT)控制. 传统的最优转矩法只考虑系统的稳态工作点,依靠系统本身的特性进行转速调节,在一定程度上限制了转速调节速度. 本文使用滑模变结构控制的思想,在最优转矩法的基础上设计得到一种变结构控制器,增大了转速跟踪过程中的不平衡转矩,缩短了系统的调节时间. 仿真结果表明本文提出的改进方法可以获得良好的转速跟踪效果,从而提高风力机的风能捕获效率.

Abstract: The optimal torque (OT) method is widely used in maximum power point tracking (MPPT) control of wind turbines due to its simplicity. The traditional OT control only considers the steady-state operating point of the system, which leads to a long tracking time. A variable structure controller is proposed based on the OT method, using the idea of sliding mode control (SMC). The proposed controller can increase the unbalance torque during the tracking and shorten the regulation time. Simulation results clearly show that a more rapid speed response can be obtained by the proposed method, while the power capture efficiency can be increased at the same time.
