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.
