   ADAPTIVE AND SELF-COMMISSIONING CONTROL FOR A DRIVE WITH INDUCTION MOTOR AND VOLTAGE SOURCE INVERTER
By R. Joetten; H. Schierling [View]
[Download]

Abstract: A control system for a drive with induction motor and voltage source inverter has been implemented, using two microprocessors. The system is self-testing, self-setting and self-adapting for optimal control response and covers a large speed range from standstill to three times base speed in the field weakening range.

   AN EXPERIMENTAL IMPLEMENTATION OF A VARIABLE-SPEED INDUCTION MOTOR DRIVE SYSTEM BASED ON MODERN ADAPTIVE CONTROL THEORY
By Akira Kumamoto; Yoshihisa Hirane [View]
[Download]

Abstract: An experimental implementation of a vector controlled induction motor variable speed drive system is studied. This system incorporates a modern control theory based on the Exact Model Matching Method and is composed of a real-time microprocessor controller, a MOSFET inverter and an inductjon motor with a speed sensor. Calculated applied voltage reference values are utilized to directly control motor terminal voltages, hence, the system eliminates any current control hardware usually required in vector control inherent uncertainty factors, such as load torque variation, insufficient decoupling due to parameter excursion and so forth, are compensated by adoption of adaptive control. Furthermore, resulting dynamic characteristics coincide with those of the model, since the system tunes itself. Through both simulation and experiments, it is confirmed that the proposed system demonstrates a good model-following ability.

   DEADBEAT RESPONSE OF FLUX CONTROL OF INDUCTION MOTOR
By Kouki Matsuse; Hisao Kubota [View]
[Download]

Abstract: The digital control of rotor flux of an induction motor with the deadbeat response is discussed. Efficiency of an induction motor is improved when the magnitude of the rotor flux is changed according to a load. However, the magnitude is usually kept constant in the field oriented induction motor control system. Because, the lower flux is, the worse response of the speed is. In order to obtain high efficiency drives of an induction motor without spoiling the speed response, a method to control the rotor flux with the deadbeat response is proposed.
