Linear induction drive system for high precision processing
This paper presents the efficiency of a position controlled linear induction drive system. The drive system consisting of personal computer, inverter and microcontroller is suitable for applications of linear induction motors with different force and speed parameter. The complete digital position control use the principle of the vector control. The microcontroller SAB 80C166 is responsible for the complete control of the drive system including pulse width modulation for the chopper and the inverter. The sampling period of the current control is fixed to lOOus. The sampling frequency of the position and speed control amounts to 500us. The software structure makes the integration of the common cascaded control and the state control possible. The experimental results demonstrate the achieved characteristic.
