Abstract

The invention discloses a motor sensorless drive control system which is applicable to a 10000-120000 RPM high-speed motor. The system mainly includes a DSP control processor, a bridge-type matrix circuit, a push-pull output drive circuit, an IGBT current-enlarging high-load bearer circuit, a high-speed sensorless detection circuit, a protection circuit, a CAN bus communication circuit, a high-low voltage isolation circuit and the like. PMSM control waveforms which are output by the DSP processor undergo power amplification through the bridge-type matrix circuit and the push-pull output drive circuit and then drive an IGBT current-enlarging module to control the high-speed motor. The system has undervoltage, overvoltage, overcurrent and temperature protection, fault memory protection, and CAN online system update program refresh functions and a fault diagnosis function which meets the ISO15765. The control system is adaptive to different kinds of permanent-magnet synchronous motors and capable of meeting control demands of new-energy automobiles at home and abroad and has characteristics of small volume, high controllable rotating speed and high efficiency.

Description

technical field [0001] The invention relates to the technical field of permanent magnet synchronous motor control, in particular to a sensorless drive control system for a high-speed motor. Background technique [0002] In traditional automobiles and industries, the control of permanent magnet synchronous motors generally has the defects of low speed, low power, slow speed response, unstable speed, and poor load capacity. With the advancement of science and technology and the continuous improvement of customer requirements, the existing technology cannot meet the customer's use requirements and national standards. For example, in the control, the accuracy of the speed is required to be less than 1%, and the response speed is less than 1s. [0003] In addition, due to the increase of peripheral ports of the control system, the standards it needs to meet are also the same as those of foreign technology frontiers. For example, the control system needs to have USB, CAN / LIN, UA...
