%0 Generic %1 sensorless_vector_control %A ?, %D 2000 %K PMSM control high sensorless speed %T Implementation of Sensorless Vector Control for Super-High Speed PMSM of Turbo-Compressor %X This paper describes the implementation of the vector control schemes for a variable-speed 131kW PMSM (Permanent Magnet Synchronous Motor) in super-high speed application. The vector control with synchronous reference frame current regulator has been implemented with the challenging requirements such as the extremely low stator inductance (28H), the high dc link voltage(600V) and the high excitation frequency(1.2kHz). Because the conventional position sensor is not reliable in super-high speed, two different schemes have been proposed to measure the position of the rotor. As a first step, a vector control with three discrete hall sensors is proposed. Because the discrete hall sensors give the rough position information with the resolution of 30, a position estimation algorithm is proposed to derive a precise position. And then a vector control scheme without any position sensor has been proposed. The proposed sensorless algorithm is implemented by processing the output voltage of the PI current regulator, and hence the structure is simple and the estimated speed is robust to the measurement noise. The experimental system has been built and the proposed control has been implemented and evaluated with and without the discrete hall sensors. The test result, up to the speed of 60,000 r/min, shows the validity of the proposed control.
