Zusammenfassung:Rotation modulation (RM) technique is mainly used in the high precision inertial navigation systems. With the rapid development of MEMS gyroscopes, rotation modulation systems based on the MEMS inertial devices have also been proposed and researched in recent years. Due to the commonly used high voltage (compare with 5V) DC motors in some of the present MEMS RM platforms, the power consumption and size make it unsuitable for the man-portable devices. In this paper, a low voltage, man-portable MEMS Rotation Modulation Platform (RMP) is proposed. A low voltage PMSM is customized to get a smooth torque and a high power density. The PMSM Vector Control (VC) algorithm is introduced to achieve the PMSM's better performance. Experiments demonstrate that the single position tracking error is less than 0.5" and the rate error of continuous rotation is less than 0.3%. Furthermore, the volume is only 110mm*150mm*50mm, the total power is less than 2 watts, which makes it an attracting rotation modulation platform for man-portable individual navigation equipment.
