电机控制中常见的控制芯片有DSP、ARM、单片机等。这些都需要根据设计的算法进行手工编程,开发周期较长。半实物仿真系统dSPACE针对这类问题提出了很好的解决方案,大大缩短了开发周期。从原理上介绍了电机控制的硬件保护和软件保护,并分析了智能功率模块IPM死区保护和dSPACE死区模块具体实现时产生的冲突。提出一种协调电路解决此问题。理论分析与制作的控制板试验结果表明,此方法可同时满足死区保护和硬件保护要求,实现IPM的正常工作。

The common control chips in motor control were DSP, ARM, microcontroller unit (MCU), etc. These chips needed to be manually programmed for motor controll applications according to the designed algorithm, and the development cycle was long. The semiphysical simulation system dSPACE offered a good solution for this problem, and on this basis, the controller development cycle was greatly shortened. We introduced the hardware protection and software protection of motor control in principle and analyzed the conflicts caused by IPM dead zone protection and dSPACE dead zone module implementation. The conflict problem was solved by using a coordination circuit. Theoretical analysis and test results of the fabricated control panel showed that this method could meet the requirements of dead zone protection and hardware protection as well as the normal operation of IPM.
