Problems solved by technology

[0005] The rotation angle of the turret is directly proportional to the rotation angle of the slewing motor, and the PID control algorithm can realize fast and high-precision tracking control; while the pitch angle of the turret and the pitch motor The rotation angle is a trigonometric function relationship, not a linear relationship, and the PID control algorithm itself is a linear control algorithm, so the PID control algorithm cannot achieve fast and high-precision tracking control

Abstract

The invention, which belongs to the technical field of follow-up control, provides a pitching angle tracking control method of a follow-up system, thereby realizing rapid and high-precision follow-upcontrol of a weapon tracking system pitching machine. According to the method, a pitch given angle value and an angle feedback value are compared through a follow-up control system to calculate an angle error; a pitching speed given value is outputted by using a feedforward+proportional differential (PD) control algorithm; the pitching angle speed given value is converted into a motor speed givenvalue by using a speed conversion equation and the motor speed given value is outputted to a motor driver to realize PID control linearization; a driver conducts speed control to drive a motor to rotate and an electric actuator cylinder is driven to stretch out and draw back, so that the rapid and high-precision target tracking control over the pitching mechanism is realized.

Description

technical field [0001] The invention belongs to the technical field of servo control, and in particular relates to a pitch angle tracking algorithm of a servo system. Background technique [0002] The follow-up system is an important part of the weapon system, and it is the basic link that constitutes the weapon automation system. The weapon tracking servo system can provide 360° azimuth angle and -10°~+70° inward target tracking for artillery and missile weapons. The follow-up control system can control the driving execution equipment to accurately track external instructions in real time according to the change of the control quantity input from the outside world. [0003] The servo system device has two degrees of freedom of turning and pitching, and is mainly composed of a base, a turning machine, a turret, a pitching machine and a launching frame. [0004] The follow-up control system receives the target angle information of the upper system, and uses the proportional...
