摘要
针对变桨伺服系统非线性、多变量、数学模型难以建立的特性,在电流环和速度环设计了自抗扰控制器,有效解决了传统PI调节器的快速性与超调之间的矛盾。仿真结果表明,电动变桨伺服系统采用以上控制方法,可以保证伺服系统有较强的抗扰性能,同时实现了无超调、响应快,具有良好的动态控制性能。
For wind power generation pitch control system has the characteristics of multivariable and nonlinear,its mathematical model is difficult to be established.The speed loop and the position loop use active disturbance rejection controller to satisfy the performance requirements of fast response and non-overshoot.The simulation results show that the intelligent control not only ensures strong anti-interference performance,but also has good dynamic performance of non-overshoot and rapid response.
