Problems solved by technology
[0011] The traditional motor controller development experiment system based on real motors only provides simple data test, display and storage functions. In addition, the motor test device is relatively independent, and PI parameter debugging only relies on manual operation. There is a lack of simulation system, and there are limitations in remote operation. , and in order to ensure the accuracy of the data, it is necessary to repeat the operation many times, the work efficiency is low, the operation is complicated, and the reliability is poor
[0012] In addition, there is no experimental system developed specifically for electric vehicle motor controllers

The invention provides an experiment system oriented to the development of a motor controller of an electric vehicle. By adding a simulation module consisting of a vehicle working condition setting module, a motor control algorithm submodule and a PI (Proportional-Integral) parameter setting submodule and a simulation and experiment result comparison module, the traditional experiment system for the development of the motor controller is optimized into an intelligent and digital experiment system oriented to the development of the motor controller of the electric vehicle. Through comparison, users can conveniently analyze or verify the performance. After comparison is made, parameters with better effects can be directly downloaded into a DSP (Digital Signal Processor) to realize verification during actual motor operation. The experiment system oriented to the development of the motor controller of the electric vehicle realizes the simulation verification of various electric vehicle motor control algorithms and realizes the optimization of control algorithms and PI parameters through comparative analysis with control effects of actual motors.
Description
technical field [0001] The invention belongs to the technical field of motor controller development, and more specifically relates to an experimental system for the development of electric vehicle motor controllers. Background technique [0002] Energy and environmental issues have given birth to the development of electric vehicles. As a key component of the motor controller, its performance directly affects the industrialization process of electric vehicles. College students majoring in motor control in colleges and universities carry out relevant experimental courses on motor drive control algorithms, and R&D company teams related to electric vehicle motor controllers need a set of intelligent , digital, networked motor controller development experiment system. [0003] At present, the relevant development experiment system is generally divided into observation experiment system based on actual motor control, and semi-physical simulation system based on Dspace. The sem...
