Abstract

The invention discloses an adaptive rate parameter setting method of a model reference adaptive permanent-magnet synchronous motor speed sensorless control algorithm. According to the method, an open-loop transfer function of a system is obtained by linearization on a reference adaptive model and a stability condition thereof, a cutoff frequency and a phase of an open-loop system are calculated bycombining a gourdain method, a stable condition of the open-loop system is given out by combining an automatic control theory, and the adaptive parameter adjustment method is given out when the cutoff frequency and phase margin do not conform to a relevant condition. With the adoption of the method, and adaptive parameter setting of the model reference adaptive permanent-magnet synchronous motorspeed sensorless control algorithm can be achieved very well.

Description

technical field [0001] The invention belongs to the field of speed sensors of permanent magnet synchronous motors, and more specifically relates to a parameter setting of adaptive rate of a speed sensorless control algorithm of permanent magnet synchronous motors based on model reference self-adaptation. Background technique [0002] Permanent magnet synchronous motors are widely used in production and life because of their advantages such as high power density, high efficiency, high reliability and simple control. In the field-oriented control of permanent magnet synchronous motor, the information of speed and rotor position is essential. However, the installation of mechanical sensors will increase the complexity and cost of system hardware, and the installation of encoders will increase the axial length of the motor. Therefore, the realization of permanent magnet synchronous motor speed sensorless control has high practical application value, and has received a lot of at...
