Title:
PERMANENT MAGNET SYNCHRONOUS MOTOR SPEED CONTROL METHOD CONSIDERING CURRENT SATURATION AND INTERFERENCE SUPPRESSION
Document Type and Number:
WIPO Patent Application WO/2022/087799
Kind Code:
A1
Abstract:
A permanent magnet synchronous motor speed control method considering current saturation and interference suppression, aiming at effectively ensuring that a motor current is always within a given range, avoiding the problem of control performance degradation caused by a current in a saturated state, ensuring system security, using no motor quantities which are difficult to obtain, such as motor acceleration, and effectively estimating and compensating for interferences in a permanent magnet synchronous motor system, such as parametric uncertainties and unknown load torque disturbance, thus finally implementing the rapid and accurate control of a motor rotating speed. In practical industrial applications, there is no need to configure a plurality of sensors, thus not only facilitating reducing the cost of system build-up, but also improving system stability. In summary, the technical solution has important practical application significance.
