For precision control of Induction Motor with Voltage Source PWM Inverter, the current component should be converted into the voltage one.
We are in difficulties for precision control with simple current feedback control because of the oscillation in system and torque ripple on high speed rotation and transient switching resulted from the disturbance which is generated by the mutual interference between d-axis and q-axis during conversion.
This paper propose linearized Decoupling Control Theory in Field-Oriented Control and presents controllable system with Microcomputer software in the whole control system.
In addition, by experiment it is proved that the system is controlled well in both steady and transient states.
The proposed system is expected to be applied in industrial AC Servo System.
