| Abstract |
This paper compares the developed estimation approaches to sensorless control of wound rotor synchronous motor drives. The proposed rotor position estimation strategy is motivated by principle function of a resolver. The rotor circuit is fed by controlled three-phase bridge rectifier which produces an ac component of frequency of 300Hz. This is an injection signal. Its response on the stator can be evaluated by Phase lock loop (PLL) or simplified Kalman filter which estimates the rotor position. These two estimation strategies are in detail compared in this contribution. The comparison, theoretical foundations and conclusions are supported by both simulation and experimental results made on developed drive prototype. |
