고속철도 영구자석 구동시시스템의 자속추정방식을 이용한 센서리스 제어

In this paper possibility of the sensorless control application using flux estimation approach to the IPMSM based next generation high speed railway system is investigated. The next generation high speed railway system is a power distributed type and uses vector control method for motor speed control. The sensorless control algorithm based on flux estimation approach is applied to the vector controller using the IPMSM based next generation high speed railway system parameters. Simulation programs based on Matlab/Simulink is developed. Finally the sensorless controller characteristics are analyzed by the simulation results.
