Correction control circuit and control method of ballistic correction projectile based on permanent magnet generator

Abstract

The invention discloses a correction control circuit of a ballistic correction projectile based on a permanent magnet generator. A power generation winding is connected with a single-phase uncontrolled rectifier circuit, the single-phase uncontrolled rectifier circuit is connected with a DC-DC circuit and is also connected with a stabilized power supply and then is connected with a digital controller; the output of the control winding is connected with a three-phase uncontrolled rectifier circuit and is connected with a load circuit through a second power switching tube; and a detection winding is connected with the digital controller through a detection circuit, and the digital controller is connected with a projectile posture resolver through a communication circuit. The invention further discloses a correction control method of the circuit. The method comprises the following steps: firstly recording, by the digital controller, a target location of the projectile, after the projectile is emitted, the correction system is powered on, measuring, by the digital controller, the rotating speed of the generator through the detection winding, calculating the deviation between the actualtrajectory and a predetermined trajectory, and finally, correcting, by the digital controller, the trajectory of the projectile in combination with the deviation and the rotating speed of the generator. By adoption of the correction control circuit and control method disclosed by the invention, the accuracy and rapidity of the correction process are improved.

Description

technical field [0001] The invention belongs to the technical field of computer application power electronics, and relates to a correction control circuit and a control method of a ballistic correction projectile based on a permanent magnet generator. Background technique [0002] In the context of the application requirements of modern warfare, along with fierce competition, how to improve the shooting accuracy of shells and reduce ammunition consumption has become a key issue in improving the practicability of ammunition. Therefore, ballistic correcting ammunition has emerged as the times require. It has the advantages of low cost, long range, and mass production, and the ballistic correction bomb is extremely suitable for the needs of modern warfare. At present, the development of domestic correction missile correction technology is relatively slow, and some progress has been made in the technical aspects of completing two-dimensional ballistic correction functions based ...
