| Abstract |
This paper presents a scheme of Model Reference Adaptive System (MRAS) method for the sensorless control of PM synchronous motors. The stability of this scheme is guaranteed by the Popov Super Stability Theorem. Two-phase stator currents and DC bus voltage are used to estimate the rotor speed and position and the algorithm is very simple. The experimental results show that the estimated values of speed and position are in close agreement with those obtained from an encoder. Through simulation and experiments, this method’s robustness to initial rotor position errors is also discussed. |
