Abstract:In order to detect the initial rotor position of an interior permanent magnet synchronous machine(IPMSM) at zero speed,based on analyzing the mathematic model of an IPMSM excited by a set of high-frequency signals,a rotor position self-estimation method based on saliencytracking is investigated in the paper.The high-frequence voltage-signal injection methods,the rotor position signal process and the position tracking observer design are discussed in detail.The simulation results demonstrate the rotor position can be detected correctly,and the motor can start reliably.
