摘要:
 针对感应电机无速度传感器矢量控制中速度和磁链的观测问题,设计了一种感应电机速度和磁链的分数阶滑模观测器,该观测器综合了分数阶积分和滑模控制的优点。观测器以定子电流观测误差构成滑模面,根据李雅普诺夫定理证明了观测器的收敛性和稳定性,并设计了分数阶滑模控制律。将该观测器应用到了感应电机矢量控制系统中,实现了无速度传感器矢量控制。仿真试验表明,分数阶滑模观测器能有效减小滑模观测中的抖振,对磁链和速度有较高的动态辨识能力。而且,无速度传感器矢量控制系统在全速范围内较好的动态和稳态性能。
Abstract:
 A rotor flux and speed estimator based on fractional-order sliding-mode was proposed for speedsensorless vector controlled induction motor drives. Advantages of fractional integral and sliding mode con-trol were synthesized by the observer. The error between the measured and estimated stator current was u-tilized to define the sliding surface,the convergence and stability of the observer were proved by the Lya-punov stability theory,and then the control law was designed. The sensorless vector control using fraction-al-order sliding-mode observer was achieved. The simulations results illustrate that the designed observercan efficiently eliminate the chattering phenomena which exist in traditional sliding-mode observer and hashigher dynamic recognition for flux and speed. Moreover,the sensorless vector control system has gooddynamic and stable performance in the full speed range.
