Abstract

The invention relates to a missile-borne intelligent vibration control electric steering engine and a control method, and belongs to the technical field of missile-borne electric steering engine control. The engine and the method solve the problems that an existing missile-borne electric steering engine is difficult to adjust the frequency in real time according to missile vibration environment changes, the flutter phenomenon is likely to occur, and the reliability is low. The engine comprises a motor driver used for driving a motor, and the motor drives a reduction gear pair to rotate and then drives a transmission pin fixed on a ball screw pair to slide in a shaft sleeve pair to drive the shaft sleeve pair to rotate; a position sensor collects position information of the shaft sleeve pair; a piezoelectric actuator is used for applying driving voltage to a piezoelectric element, and the piezoelectric element outputs corresponding driving force or driving displacement to adjust the frequency state of the missile-borne steering engine; the piezoelectric element is further used for collecting an acceleration signal of the missile-borne steering engine; a controller assembly is used for generating a motor control signal for controlling the motor driver according to the position information and a rudder deflection control instruction; and a vibration control module is used for generating a vibration control signal for controlling the piezoelectric actuator according to an acceleration signal.

Description

technical field [0001] The invention relates to the technical field of control of an electric steering gear for launching, in particular to an intelligent vibration control electric steering gear for launching and a control method. Background technique [0002] With the increase of the output power of the catapult electric steering gear, the volume of the main components of the catapult rudder increases and the rigidity drops sharply. It is more and more sensitive to the vibration environment, and even has caused serious harm. Moreover, at various stages of missile flight, such as the engine ignition moment, booster engine separation moment, and missile attitude adjustment, the vibration environment of the electric steering gear on the missile will change greatly, which will have a great impact on the performance of the steering gear. Significant impact, even beyond the tolerance range leading to functional failure. [0003] At present, the traditional electric steering ge...
