摘要
Abstract
This paper adopts the method of high-frequency rotating voltage injection to estimate the rotor position and speed,which realizes the position sensorless control of the permanent magnet synchronous motor and eliminates adverse effects such as increased cost and reduced reliability brought by mechanical position sensors.The full text first models the high-frequency model of the permanent magnet synchronous motor,then analyzes the basic principles of the rotating high-frequency voltage injection method,and then analyzes the factors that affect the accuracy of position estimation,and finally builds a simulation platform to verify the proposed strategy.关键词
