Abstract

The invention discloses a motor driving system and method based on digital and analog hybrid simulation. The system comprises a single-chip microcomputer A, a single-chip microcomputer B and analog quantity signals connected between the single-chip microcomputer A and the single-chip microcomputer B; and the A machine simulates a motor control algorithm, the B machine realizes the function of a digital motor, and intermediate connection signals are SVPWM, motor current and motor rotating speed signals which can be observed through an oscilloscope. The system adopts the machine A to realize FOC control of the motor, adopts the machine B to realize digital IGBT and PMSM motors, can flexibly change motor parameters and load torque, replaces an actual motor to carry out various experiments, has small errors between obtained test data and actual data, can replace the actual motor in the experiments, and is also suitable for beginners of motor control. The FOC control algorithm and program of the motor can be verified conveniently, and the simulation and debugging efficiency is improved. The price of the single-chip microcomputer is far lower than that of an actual motor, the motor testing cost can be greatly reduced, and the safety is improved.

Description

technical field [0001] The invention belongs to the technical field of motor control, and in particular relates to a motor driving system and method based on digital and analog mixed simulation. Background technique [0002] Motor parameter debugging and detection is an important demand for college student experiments and related industry practitioners. However, in actual operation, the existing motor test platform is high in cost, not flexible enough, and has certain risks. When testing or verifying the control algorithm with an actual motor, the motor is damaged or more serious accidents are often caused by algorithm defects or operational errors. As a result, some students and personnel cannot carry out actual operation practice due to insufficient experimental conditions. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention provides a motor drive system and method based on digital and analog mixed simulation, which...
