In this research, one of the purpose of our work is to present a speed-sensoeless vector control method for an induction motor operating at high efficiency and high response, in which core loss is taken into account, and discusses the system's performance for electric vehicle drives. The proposed vector control system consists of a speed-adaptive rotor-flux observer which takes core loss into account and employs a direct-field-oriented control scheme which compensates for the influence of core loss. On the basis of simulation and experimental results, the author shows that the proposed system can estimate motor speed even when the rotor flux is changed.The next results of this research is to propose that a method of improving the stability of parallel-connected multiple-induction motor drive system fed by a 3-leg single inverter has been devised that employs the averages and differences of estimated parameters for field-oriented control. The parameters and variables of each motor (stator current, rotor flux, and speed) are estimated using adaptive rotor flux observers to achieve sensorless control. The validity and effective of the proposed method have been demonstrated through simulations and experiments. The experimental results show that the proposed method is useful under the condition that the ratings of each induction motor are different.In addition, this research presents an independent vector control method of parallel-connected two. induction motors by using. a new PWM method of a 5-leg single inverter. In order to achieve independent control of both induction motors using the leg connected in common, the author adopted a particular PWM strategy which can reduce unnecessary switching in each leg. Simulation results show that the proposed method is effective under various driving conditions.

在这项研究中，我们工作的目的之一是提出一种考虑铁芯损耗的高效、高响应感应电机无速度传感器矢量控制方法，并讨论该系统在电动汽车驱动中的性能。所提出的矢量控制系统由速度自适应转子磁通观测器组成，该观测器考虑了磁芯损耗，并采用直接磁场定向控制方案来补偿磁芯损耗的影响。在仿真和实验结果的基础上，作者表明，即使转子磁链发生变化，所提出的系统也可以估计电机速度。本研究的下一步结果是提出一种提高由三桥臂单逆变器供电的并联多感应电机驱动系统稳定性的方法，该方法利用估计参数的平均值和差值进行磁场定向控制。使用自适应转子磁通观测器估计每个电机的参数和变量（定子电流、转子磁通和速度），以实现无传感器控制。通过仿真和实验证明了该方法的有效性和有效性。实验结果表明，该方法在各异步电机额定值不同的情况下是有效的。此外，本研究提出了一种并联两台独立矢量控制方法。使用感应电机。一种新的 5 桥臂单逆变器 PWM 方法。为了使用共同连接的支路实现对两个感应电机的独立控制，作者采用了特殊的 PWM 策略，可以减少每个支路不必要的切换。仿真结果表明，该方法在各种驾驶条件下都是有效的。
