High-precision control system of sounding rocket emission device

Abstract

The invention provides a high-precision control system of a sounding rocket emission device. The full-automatic erection and rotation function of the sounding rocket emission device can be achieved, the beneficial effects of being easy to operate, high in precision, high in response, high in reliability, good in safety performance and the like are achieved, according to the control system, closed-loop control is adopted in an erection device and a rotation device of the emission device, and the problems that due to hydraulic system pressure drop, the erection angle deviation, large cost, poorsafety, and difficult maintaining happen are solved. During use, initial pitching angle calibration is carried out through a tilt angle sensor, a control unit is used for giving the relative rotationangle to a pitching encoder, a closed-loop control emission device reaches the set target pitching angle, the directional precision of the pitching angle reaches 0.1 degree, the rotation device is driven by a servo motor, during use, firstly, a dual GPS system achieves the initial autonomous direction, a control unit is used for giving the relative rotating angle for a direction encoder, the servomotor drives the rotation device to achieve direction adjustment, the direction angle orientation accuracy reaches 0.2 degree, accordingly, and high-precision control over the pitching angle within the range of 0 to 90 degrees and the direction angle within the range being + / -180 degrees of the emission device can be achieved.

Description

technical field [0001] The invention relates to a control system, in particular to a high-precision control system for a sounding rocket launching device. Background technique [0002] The traditional rocket launch actuator is a hydraulic cylinder in the hydraulic system, which pushes the vertical arm to complete the vertical action. It needs to be equipped with a hydraulic system, and the load size and direction of the hydraulic cylinder will change during the launch preparation process, which will cause launch jitter and easily damage the equipment. In addition, the traditional rocket erection uses a quadrant to observe the change of the pitch angle. When it is close to the launch pitch angle, it uses manual fine-tuning to make it reach the launch pitch angle; the rocket shooting direction is determined by theodolite measurement; it does not have an automatic adjustment function. [0003] In order to meet the larger, faster, more accurate and safer new sounding rocket mis...
