Embodiment

[0032] The whole of the present invention includes MCU chip, digital display screen, button, function signal generator and whole development board shell.

[0033] Connect the A and B phases of the encoder of the motor to the pin header of the speed detection port 6, and the other two pin headers are used to supply power to the motor encoder. Connect the positive and negative poles of the motor to the pin header of the motor voltage detection port 5, which is used to provide the motor with a frequency sweep signal and continuously record the real-time voltage.

[0034] After turning on the power, use the direction key 2 to select the system identification mode and select the identification parameters, press the key 3 to confirm, start to power on the motor and detect the real-time voltage and speed of the motor.

[0035] After two frequency sweep time periods, the system automatically processes the data and then calculates the system identification model and displays it on the ...

Abstract

The invention discloses a development board for small motor identification, which comprises an MCU chip, a motor voltage detection port, a motor speed detection port, a digital display screen, a communication chip and a power supply chip, and the MCU chip is used for processing input motor voltage and speed signals to obtain a required transfer function; the motor voltage detection port is used for detecting the real-time voltage of the motor; the motor speed detection port is used for detecting the real-time rotating speed of the motor; the communication chip is used for information exchange between the upper computer and the MCU; the digital display screen is used for setting identification requirements and displaying transfer functions; the power supply chip is used for stabilizing voltage and current on the development board. According to the invention, the transfer function of the small direct current motor can be conveniently detected, different identification requirements can be realized through interaction of the digital display screen and the MCU, the rotating speed and the voltage of the motor can be detected in real time, complicated motor identification experiments and later data statistics and processing are simplified, and a large amount of time and resources are saved.

Description

technical field [0001] The invention relates to the field of model identification of small motors, in particular to a development board for identification of small motors. Background technique [0002] With the continuous improvement of the modern control field, the accuracy of the system model is required to be higher and higher, and the system identification has become a key link in the control field. [0003] When identifying and modeling a small motor system, it is necessary to measure its speed characteristics, but the motor-to-drag experiment is more complicated, the cost is higher, the reusability is poor, and the construction period is longer, which will waste a certain amount of manpower and resources. Specifically, for different types and sizes of tested motors, it is necessary to design special motor drive circuit boards and equipment fixtures; at the same time, for different identification requirements, it is also necessary to modify the parameters of the identif...
