In this paper, a recently proposed analytical fractional order PID controller design approach is applied to control the speed of a two-mass wind turbine system. The wind turbine complex nonlinear system is commonly modeled as a two-mass system because of its inherent advantages. On the other hand, wind turbulence and high overshoot are factors that cause stress in wind turbines which may be alleviated using an adequate speed control strategy. The applied technique allows the design of the fractional order PID parameters according to desired specifications in terms of phase margin and unity gain crossover frequency. The main advantage of using such tuning method is that the closed loop system behaves as Bode's ideal transfer function. Simulation results show the higher performance of the fractional order PID controller design technique when compared with computational tuning approaches in terms of multiple performance evaluation indices.

在本文中，最近提出的分析分数阶 PID 控制器设计方法被应用于控制两质量风力涡轮机系统的速度。由于其固有的优势，风力涡轮机复杂非线性系统通常被建模为二质量系统。另一方面，风湍流和高超调是导致风力涡轮机应力的因素，可以使用适当的速度控制策略来减轻这些应力。所应用的技术允许根据相位裕度和单位增益交叉频率方面的所需规范来设计分数阶 PID 参数。使用这种调谐方法的主要优点是闭环系统表现为波德理想传递函数。
