Abstract

The invention provides a tank gun control servo control method based on an auto-disturbance rejection control technology, which can improve the dynamic firing accuracy and the weapon stabilization accuracy of a fire control system. The tank gun control servo control method comprises the following steps: step 1, establishing a large-caliber gun turret control model; step 2, designing a tracking differential controller in a horizontal stabilizer based on the auto-disturbance rejection control technology according to the control model established in the step 1; step 3, designing a third-order extended state observer (ESO) according to the large-caliber gun turret control model put forward in the step 1 to estimate the disturbance of the system and compensate in real time; step 4, obtaining a differentiation between an error e1 and an error e2 according to the obtained large-caliber gun turret control model; and step 5, obtaining a system control law according to an auto-disturbance rejection control principle after a nonlinear feedback law is designed.

Description

technical field [0001] The invention belongs to a horizontal direction and a vertical direction control method of a tank gun control system, and relates to a tank gun control servo control method based on an active disturbance rejection control technology. Background technique [0002] The tail compartment loading machine is a direction of the development of tank armored vehicles, and now a variety of tanks are equipped with the tail compartment loading machine. Due to the change of the amount of ammunition during the battle, the weight and inertia of the turret and the position of the center of gravity will change greatly, which exceeds the adjustment and adaptability of the fire control system, resulting in a decline in system performance and even affecting the stability of the control system. Combat effects. Therefore, it is necessary to study a solution to this problem, so that the tank has a good control effect during the entire battle, under the condition of full ammu...
