Abstract

The invention provides a brushless electric machine single-chip microcomputer control system and a brushless electric machine fuzzy controller creation method. The brushless electric machine single-chip microcomputer control system comprises a micro-controller, a serial communication circuit, a logic circuit, a driving circuit, a detection circuit, a power source and an electric machine. The micro-controller is connected with the logic circuit and the detection circuit. The power source supplies power to the micro-controller, the logic circuit and the driving circuit. The detection circuit is also connected with the logic circuit, the driving circuit and the electric machine. The micro-controller is connected with a PC machine through the serial communication circuit. Lower computers transmit measured information such as the electric machine rotating speed, voltage and current to serial ports of the PC machine through serial ports through a certain data format. The upper computer obtains the values of the electric machine rotating speed, voltage and current after receiving the data. The system better realizes self-adaptive tracking of a datum speed reference module and has the advantages of flexible control, high adaptability, high control accuracy and high robustness.

Description

technical field [0001] The invention belongs to the field of automatic control, and in particular relates to a single-chip microcomputer control system for a brushless motor and a method for establishing a fuzzy controller thereof. Background technique [0002] In the prior art, a relay circuit is usually used to connect to the input end of the motor, so as to control whether the motor starts. The output end of the motor is connected to the on-off energy storage switch in the high-voltage equipment, so as to control the closing or closing of the on-off energy storage switch, and then achieve the purpose of remotely controlling the off or on-off of the on-off energy storage switch. However, the relay circuit has the following disadvantages: 1. Since there are many components and thread ends in the relay circuit, the wiring of the relay circuit is complicated. Artificial wiring assembly is not only inefficient, but also easily causes the relay circuit to fail to work normally...

AI Technical Summary

Problems solved by technology

However, the relay circuit has the following disadvantages: 1. Because there are many components and wire ends in the relay circuit, the wiring of the relay circuit is complicated

Manual wiring assembly is not only inefficient, but also easily causes the relay circuit to fail to work properly due to wrong wiring

2. Since the relay circuit has no protection circuit, once the motor is blocked, the relay may be burned

However, the existing fuzzy controller design and parameter online adjustment are insufficient
