摘 要:由于风力发电机变桨系统是一个非线性、多变量和强耦合的控制系统,为了解决变桨伺服电机的控制精度问题,本文提出了一种基于趋近律的滑模控制策略,利用Matlab软件平台对该策略进行了仿真试验研究。仿真结果表明,采用基于趋近律的滑模控制技术不但提高了变桨距系统的控制精度,同时还增强了系统变桨同步性。 关键词:变桨控制;伺服控制;滑模控制;控制精度;同步性 Abstract: Due to the wind turbine pitch system is a non-linear, multivariable and strong coupling control system, to address the pitch-controlled precision of servo motor, the rate reaching law sliding mode control strategy was presented based on reaching, and conducted a simulation experimental study by Matlab software platform. Simulation results show that rate reaching law sliding mode control technology improves the control of variable-pitch system accuracy, and enhances the system of pitch-Synchronization.
