本文针对磁场定向感应电机驱动，提出了一种新的滑模无位置传感器控制算法。在该算法中，感应电机电流模型中包含磁链、速度和转子时间常数的项在电流方程和磁链方程中都是常见的，通过滑动函数来估计。当实际电流和观测电流之间的误差收敛到零时，保证了磁链和速度估计的精度。因此，将四阶系统简化为两个二阶系统，使得速度估计变得非常简单，并且对参数不确定性具有很强的鲁棒性。仿真和实验结果验证了该方法的有效性。
In this letter, a new sliding-mode-sensorless control algorithm is proposed for the field-oriented induction machine drive. In the proposed algorithm, the terms containing flux, speed, and rotor time constant, which are common in both current and flux equations, in the current model of the induction machine are estimated by a sliding function. The flux and speed estimation accuracy is guaranteed when the error between the actual current and observed current converges to zero. Hence, the fourth-order system is reduced to two second-order systems, and the speed estimation becomes very simple and robust to the parameter uncertainties. The new approach is verified by simulation and experimental results.
