Embodiment Construction
[0026] based on the following Figure 1 ~ Figure 3 , specifically explain the preferred embodiment of the present invention.
[0027] The servo system of a new-generation launch vehicle uses existing resources according to the space layout requirements and uses two independent small position sensors (single weight 15g). The two position sensors 101 are distributed on both sides of the output shaft of the servo mechanism. Detect the swing angle output of the servo mechanism.
[0028] Such as figure 1 As shown, the structure of the position sensor 101 is similar to a sliding rheostat. The position sensor 101 has a feedback negative power supply terminal 1, a feedback positive power supply terminal 3 and a feedback output terminal 2, and the feedback negative power supply terminal 1 and the feedback output terminal 2 Between the A-B section resistance matrix, between the feedback positive power supply terminal 3 and the feedback output terminal 2 is the B-C section resistance m...
