Vector Control System Based on Single Neuron PI for Linear Induction Motor

This paper introduces a frequency variable control system for elevator driven by linear induction motor,and this elevator has been tested.In this system,chip TMS320F240 are used which is special for motor control.Considering the speed tracking effect is not so satisfactory and the intrinsic end effect of linear induction motor,we present a method for constructing the mathematical model of this motor to compensate the end effect,and develop a field oriented control system based on single neuron PI for linear induction motor driven elevator,then have this model simulated and tested.The results are provided to verify that this mathematical model is effective and the control algorithm is robust against parameters variation and load change.
