Abstract

This paper reviews on parameter estimation techniques in decoupling control of induction motor drive. The sluggish transient performance of voltage/frequency (V/Hz) control of induction motor drive is of course overcome by traditional decoupling control, where three phase quantities are transformed into two phase quantities. The controller performance in decoupling control is nevertheless affected by temperature variation. It is well-known that temperature variation will affect the rotor and stator resistance variations in the drive, and hence mismatches the values of rotor and stator resistances in the controller. Therefore, the performance of the drive is degraded in terms of torque, flux and currents in decoupling control. Efforts are made to improve the performance of the drive by estimating and adapting the temperature dependent parameters. The paper reviews the various online stator and rotor resistance estimation methods including soft computing techniques to improve the performance of the drive.
感应电机驱动解耦控制中的参数估计技术综述
综述了异步电机驱动解耦控制中的参数估计技术。传统的解耦控制将三相量转化为两相量,克服了感应电机驱动电压/频率(V/Hz)控制的瞬态迟滞性能。在解耦控制中,控制器的性能受到温度变化的影响。众所周知,温度的变化会影响驱动器中转子和定子电阻的变化,从而导致控制器中转子和定子电阻的值不匹配。因此,在解耦控制中,驱动器的转矩、磁链和电流的性能都有所下降。通过估计和适应与温度相关的参数,努力提高驱动器的性能。本文综述了各种在线定子和转子电阻估计方法,包括软计算技术,以提高驱动器的性能。
