Position-Sensorless Control Mode for UUV's Propulsive Motor
摘要
Abstract
Permanent magnet motor has been extensive used as unmanned underwater vehicle's propulsive motor with the advantages such as small-volume, light-weight and high power density, and the sensorless technique is one of development direction of permanent magnet motor variable-speed system.Two typical direct estimation methods of speed and rotor position are analyzed and a novel sensorless technique in permanent magnet motor direct torque control (DTC) system is put forward in this paper.By calculating stator flux angle and torque angle, then subtracting torque angle from stator flux angle to obtain the rotor position and velocity, and using improved integrator instead of traditional one, this novel technique can restrain origin drift and improve estimation accuracy of speed and rotor position in DTC system.The result of simulation and test shows that good control performance can be obtain in permanent magnet motor DTC system by using this new technique.关键词
