Abstract

The invention discloses a control system used for a fixed wing canard rudder, and the control system replaces the head of a mortar projectile to fuze, and is mounted on the head of the mortar projectile. The control system comprises a control mechanism system, an attitude measurement system, a wireless communication system and a processor, wherein the control mechanism system comprises electronic load, a rectifying bridge and a permanent magnet motor; the attitude measurement system is used for transmitting acquired rolling angular velocity to the processor through the wireless communication system; the processor is used for controlling the electronic load according to rotation speed difference between the wing canard rudder and a projectile body; and electromagnetic torque of the permanent magnet motor is regulated through the rectifying bridge, so that rolling angular velocity of the fixed wing canard rudder is changed. According to the control system disclosed by the invention, the electromagnetic torque of the permanent magnet motor and the rolling angular velocity of the fixed wing canard rudder are changed, so that the control force vector direction of the canard rudder is changed; mass centre motion is corrected by motion around a mass center, so that fall point precision of the mortar projectile is improved; and moreover, a conventional servo mechanism is cancelled, so that the size and the cost of the control system can be greatly reduced, and therefore, the control system has the characteristic of a high cost-benefit ratio.

Description

technical field [0001] The invention relates to the aerospace field, in particular to a control system for a fixed-wing canard. Background technique [0002] Mortars have the characteristics of curved trajectory, fast rate of fire, simple structure, easy maneuverability, and easy operation. They are suitable for urban street fighting and mountain warfare, and have been widely used in countries all over the world. In the prior art, the cross duck rudder is mainly used to realize the precise guidance of the projectile, but this method is costly and the control is relatively complicated. Contents of the invention [0003] Aiming at the above-mentioned defects in the prior art, the present invention provides a control system for fixed-wing canards, which improves the drop point accuracy of the mortar. [0004] The present invention provides a control system for fixed-wing canards, which is improved in that the control system includes a control mechanism system, an attitude me...
