Abstract

The invention relates to a permanent magnet synchronous machine control system based on a high-order sliding mode method. The system is characterized by comprising the components of a Cark transformation module, a Park transformation module, a rotary transformer, a high-order sliding mode observer, a two-order supercoiling sliding mode controller, a first comparator, a second comparator, a permanent magnet synchronous motor d-axis current loop proportional plus integral controller, a permanent magnet synchronous motor q-axis current loop proportional plug integral controller, a Park inverse transformation module, a pulse width modulation module and an inverter. The permanent magnet synchronous machine control system can quickly and effectively adjust various input parameters and output parameters of the permanent magnet synchronous motor on the condition that an interference occurs, and furthermore realizes high dynamic response speed and high robustness. Furthermore the permanent magnet synchronous machine control system improves control precision and operation reliability of the permanent magnet synchronous machine.

Description

technical field [0001] The invention relates to the technical field of permanent magnet synchronous motors, in particular to a permanent magnet synchronous motor control system and control method based on a high-order sliding mode method. Background technique [0002] In recent years, with the development of rare earth permanent magnet materials and power devices, permanent magnet synchronous motors (Permanent Magnet Synchronous Motor, PMSM) have received extensive attention for their high performance, high torque inertia ratio and high energy density, especially The decline in the price of permanent magnet materials and the improvement of magnetic properties have greatly promoted the development and application of permanent magnet synchronous motors. In recent years, the permanent magnet synchronous motor system is playing an increasingly important role in the servo system with high precision and wide speed range. Permanent magnet synchronous motor is a multivariable, stro...
