Abstract :
This paper designed a slide-mode observer with gain switch controller rules.The stability of system analyzed by using Lyapunov theory. The variations of the parameters are analyzed.Using the sensorless control system of PMSM based on TMS320LF2808 as example, the experimental results prove that this observer is robust to parameter variation and able to observe the position of rotor.
