摘要: 
This paper develops methodologies for current control, experimental modeling and velocity
tracking of a laboratory-based single-sided, short-stator linear induction motor. A constant frequency,
three-phase pulse-width-modulation (PWM) current controller is constructed to improve the current
quality and power factor for the motor. Several current control experiments with step set-point changes
are performed to obtain the current loop transfer function with uncertainty parameters. To overcome
the performance degradation caused by parameter variations in the motor due to increased temperature
in the reaction rail, a two-degree-of-freedom controller, consisting of a pre-filter and a
proportional-integral-derivative (PID) feedback controller, is designed to produce good velocity
tracking performance, robustness and disturbance rejection. The experimental setup consists of a
laboratory-based linear induction motor, a ramp comparison PWM current inverter, a precise Laser
displacement instrument, a host computer IBM PC486 and a digital signal processor (DSP)
TMS320C31 with three l6-bit analog-to-digital converters (ADCs) and digital-to-analog converters
(DACs). Both current control and velocity tracking algorithms are implemented using the DSP
processor and standard C programming techniques. Experimental results demonstrate that the proposed
velocity tracking method is capable of providing a good result on the motor.
