Abstract

The application provides a HIL simulation test method and system; the method comprises the following steps: collecting feedback current between a motor driver and a motor controller, and forming a feedback control law according to the feedback current and a preset reference current; collecting bridge arm voltage of the motor driver, and forming a feedforward control law according to the bridge arm voltage and a preset filter; forming a composite control law according to the feedback control law and the feedforward control law, and controlling a motor simulator to carry out HIL simulation test for a tested controller according to the composite control law. The feedforward control law can improve the system dynamic response speed, the feedback control law can adjust system errors, and the composite control law formed by the feedforward control law and the feedback control law can allow the feedback current to better track the reference current, thus improving the motor simulator current tracking precision, and improving the dynamic tracking performance.

Description

technical field [0001] The present application relates to the field of simulation technology, in particular to a HIL simulation test method and system. Background technique [0002] With the continuous development of hybrid electric vehicles and pure electric vehicles, the complexity of motor control strategies is increasing, and the demand for the development environment of motor controllers is also increasing. During the research and development process of the motor controller, control function testing, fault injection testing, CAN communication testing, etc. are required. The HIL (Hardware-in-the-Loop, hardware-in-the-loop) simulation test system can be used to test the motor controller. [0003] The HIL simulation test system uses a real-time processor to run the simulation model of the motor simulator to simulate the running state of the controlled object, and conducts comprehensive and systematic tests on the tested controller. The HIL simulation test system can compl...
