摘要:
针对坐标旋转法永磁同步发电机无速度传感器控制中忽略定子电流微分项带来的估计偏差大等问题,提出基于旋转坐标系的自适应锁相环和滑模辨识方法。采用近似滑模控制对模型电机定子电流进行控制,使发电机和模型电机电流相等,从而获得两电机转子相位差的正弦和余弦分量。建立直驱式永磁同步电机无速度传感器辨识模型和自适应锁相环模型,并利用基于反步法的自适应锁相环进行速度和相位观测,在此基础上利用Lyapunov函数设计法设计控制器。采用近似滑模辨识使模型电机电流快速逼近原电机电流且到近似正弦的控制量,自适应数字锁相环相位收敛快,采用Lyapunov函数设计的控制器能保证系统收敛。仿真结果验证了该方法的可行性和有效性。
Abstract:

【Abstract】 Aiming at the big error problem of speed sensorless permanent magnet synchronous generator(PMSG) control with rotating frame by omitting differential component in direct-driven wind power system,a sliding mode observer with adaptive phase-locked loop(PLL) was presented.Model PMSG current was controlled to keep track of PMSG current by approximate sliding mode observer(SMO) and rotor phase difference of two machine were acquired.Speed and phase were observed by adaptive PLL with acquired sine and...
