Abstract

The invention discloses a three-phase AC motor virtual-simulation experiment system and experiment method of hardware-in-loop. The security of the system can be improved, the development cost is greatly reduced, and an effect same as an actual motor verification platform can be acquired, and the development cycle is shortened. The system comprises an upper computer with a human-machine interactioninterface and a power conversion unit, and further comprises a control panel and a model panel; the upper computer is connected with the model panel and the control panel through USB interfaces, thecontrol panel and the model panel are connected through a Spi interface, the control panel is connected with the power conversion unit, and the three-phase AC output by the power conversion unit is used for supplying power for the motor; the control panel produces an analog voltage signal and a PWM signal so that the model panel can simulate different motor states and controlling on-off states ofthe power conversion unit; the power conversion unit is connected with a voltage-current transformer and a rotary encoder on the motor so as to collect the voltage-current and rotating speed data of the motor.

Description

technical field [0001] The invention relates to a hardware-in-the-loop virtual simulation experiment system, in particular to a hardware-in-the-loop three-phase AC motor virtual simulation experiment system and an experiment method. Background technique [0002] The motor controller is a core component used to control functions such as starting, speed regulation, braking, and stopping of the motor. The existing motor controller is composed of a control board and a power conversion unit. The traditional development process of the motor controller is roughly as follows: 1) Establish a mathematical model for the motor system; 2) Use simulation software to conduct system analysis and control algorithm design, and pass simulation verification; 3) Hardware circuit design to realize the integration of control board and power conversion unit Test; 4) The control algorithm is downloaded to the hardware circuit, and the high-power motor is driven for debugging. The above method has t...
