Open publisher page 0 citations

Abstract

Before turning,the rotor initial position of PMSM is unknown.In order to control effectively,the rotor position must be known clearly.Simply give a direct current have serious defect in industrial scene.The method of initial rotor position under the premise of maintaining the rotor in a fixed location was got,the regression algorithm to calculate the precise initial angle and good results based on the digital platform TMS320LF2407A were achieved.
