Vector control has made it possible to control the instantaneous torque of an induction motor and is widely used in various industrial areas. The vector control will be classified into two types according to a selection of the co-ordinate system for the model of the induction motor. A synchronously rotating co-ordinate system is used for the well-known slip frequency controlled type of vector control. A stationary co-ordinate system is used for the flux observer based vector control. In this research, new flux observers based vector control systems are proposed and discussed by using both co-ordinate systems.Principal results obtained by this work are as follows;1.System analysis : The steady-state performance is analyzed and discussed. In order to analyze the robust stability, a linear model is proposed taking into account the machine parameter change. By using this model, the trajectories of poles and zeros of the torque transfer function are computed and discussed.2.Experimental system : The digital signal processor (TMS320C30) is used for the implementation of the control system. Two kinds of softwares are developed. One is an observer based vector control program written in the DSP assembly language and the other is a monitoring program written in C language.3.Computed and experiment result : The experimental results show good agreement with the conputed ones. It is confirmed that the proposed method improves the robustness comparing with the conventional one.4.Sensorless vector control : By using a full order observer, new vector control system in which the estimation of speed and resistances are possible is developed.

矢量控制使得控制感应电机的瞬时转矩成为可能，并广泛应用于各个工业领域。矢量控制将根据异步电动机模型的坐标系选择分为两种类型。同步旋转坐标系用于众所周知的滑移频率控制型矢量控制。基于磁链观测器的矢量控制采用静止坐标系。在本研究中，提出并讨论了两种坐标系下基于磁链观测器的矢量控制系统。本工作取得的主要成果如下：1。系统分析：对系统的稳态性能进行了分析和讨论。为了分析系统的鲁棒稳定性，提出了考虑机器参数变化的线性模型。利用该模型，计算并讨论了转矩传递函数的极点和零点轨迹。实验系统：采用数字信号处理器TMS320C30实现控制系统。开发了两种软件。一个是用DSP汇编语言编写的基于观测器的矢量控制程序，另一个是用C语言编写的监测程序。计算与实验结果：实验结果与计算结果吻合较好。结果表明，与传统方法相比，该方法的鲁棒性有所提高。无传感器矢量控制：通过使用全阶观测器，开发了一种新的矢量控制系统，该系统可以估计速度和阻力。
