Corrective moment controlling system based on fixed wing canard dual-spin projectile

Abstract

The invention discloses a corrective moment controlling system based on a fixed wing canard dual-spin projectile. A magazine is connected with a fairing through a three-phase permanent magnet motor. An output end of a magnetometer and the output end of a GPS module are both connected with a motor controller through a first signal conditioning circuit. The three-phase permanent magnet motor comprises a rotary transformer coil, a three-phase motor stator winding and a power supply coil, wherein the rotary transformer coil is connected with the motor controller through a second signal conditioning circuit. A power supply system is connected with a power supply interface of a MOS pipe driving circuit, the power supply coil and the power supply interface of the motor controller. The output endof the motor controller is connected with a controlling end of the MOS pipe driving circuit and the MOS pipe driving circuit is connected with a grid electrode of a MOS pipe. A drain electrode and a source electrode of the MOS pipe are connected with the three-phase motor stator winding through a three-phase bridge rectifying circuit. According to the system, the corrective moment controlling based on the fixed wing canard dual-spin projectile can be realized.

Description

technical field [0001] The invention relates to a correction moment control system, in particular to a correction moment control system based on a fixed-wing canard double-rotor bomb. Background technique [0002] In order to improve the striking accuracy of the artillery and make the projectile have a certain guidance ability, many countries and regions have carried out research on the structural design of the rotation stabilized projectile in recent years. The one-maintenance positive projectile based on the structure of increasing resistance, the two-dimensional correcting projectile based on the structure of increasing resistance and reducing rotation, the pulse correcting projectile and the sliding block correcting projectile have been developed. These cannonballs have a certain drop point correction ability by adding some actuators that can provide correction torque to the projectile body. [0003] However, because the action of the torque actuator is discrete, or eve...
