This study represents a flux observer application for permanent magnet synchronous motor (PMSM) based electric vehicle (EV) system. Getting rid of speed sensors is very important for reducing EV cost. Firstly, motor control algorithm and observer algorithm are written on Simulink environment and download to TI F28335 DSP over USB by using Simulink Embedded Coder. Then the system is tested at variable speed which is changes every 10 seconds. The results show the performance of the flux observer estimation. It is seen that the flux observer successfully estimates the actual speed in most areas only expect for transients. The effectiveness of flux observer is proven via experimental results.
