Abstract: Aiming at verifying the performance and reliability of the sensorless drive and testing the running state of PMSM under different types of the inverters fault, the hardwareintheloop simulation was proposed when we didnt have a real machine and an inverter. First of all, the mathematical model of permanent magnet synchronous motor and the speed/position estimator based on model reference adaptive system were researched. Then, a mathematical model including a PMSM, an inverter, and the hardwareinterface was built as the controlled object with MATLAB/Simulink and RTLAB. And TMS320F28027 was chosen as the controller of the PMSM, which was used to run the algorithmic logicMARS（model reference adaptive system）and FOC. On the basis of this HIL platform, the control effect of sensorless drive was verified and different types of fault was simulated. The results indicate that this hardwareintheloop simulation platform provides an effective way for the validation of sensorless control algorithm and fault simulating of inverters, and lays a good foundation for further research about the optimization of control algorithm.
