摘要
本文提出了一种新型无速度传感器交流调速系统的设计方法。它采用模型参考自适应参数辨识方法对电机转速在线辨识,采用滑模变结构非线性系统状态估计理论对电机转子磁链在线估计;理论证明,它们不仅对电机建模误差、参数变化、测量噪声有较强的(?)棒性,而且能保证辨识或估计方法的全局渐近稳定。仿真结果证明了所提方法的有效性。
This paper presents a novel design method of AC drive system of speed sensorless. It adopts MRA parameter identification for rotor speed as well as sliding mode observer for estimation rotor flux. Theory shows that the system has robustness for modelling error and varying, parameter of motor. Simulation result shows. that presented method is efficient.
