Embodiment 1
[0040] Embodiment 1, large-diameter millimeter wave / submillimeter wave telescope arc motor control system position tracking detection method and the position detection method of the present invention can realize the angular velocity of the large diameter millimeter wave / submillimeter wave telescope when running at low speed to reach 1" / s , the high speed can reach 12° / s, and the pointing accuracy can achieve ≤1〞 / s required by millimeter wave and submillimeter wave.
[0041] The technical solution for realizing the present invention is that the dual-channel multi-pole rotary transformer combined with coarse and fine is converted into a digital signal representing the absolute mechanical position signal through a digital converter, and then output to the parallel port of the DSP module after level conversion to calculate the absolute mechanical position. It is used as the position feedback signal of the position closed loop of the arc motor; it is converted into an electrical ang...
