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。

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.
Key words: pitch system；servo motor；sliding mode control；precision；synchronization
