Study of Electrical Traction Locomotive Control System Based on Feed-Forward Decoupling Strategy

Abstract:

An asynchronous motor is widely used in traction locomotive system now, AC induction motor is nonlinear, strongly coupled and multivariable system, so it is very difficult to control as a linear system. For this, VVVF(Variable Voltage Variable Frequency) control method adopt in some running traction locomotives, that can reduce over-current with load starting and should be compensated at low frequency. Based on study the Control strategies of locomotives, vector control adopt in most electrical traction locomotive. According to the drawing performance requirements of electrical traction motor, feed-forward decoupling method adopted. Simulation and experiment proved this method can meet the traction locomotive control requirements.
