Embodiment 1

[0034] figure 1 It is a schematic diagram of the structure and working principle of the traditional hydraulic control system. It can be seen from the figure that the traditional hydraulic control system directly feeds back the angle value obtained in the position loop to the position regulator and PID regulator 2. Due to the strong hysteresis and nonlinearity of each link of the hydraulic system, it causes dynamic adjustment. A series of problems such as long time, unstable system, vibration of speed ring, etc.

[0035] In order to solve the shortcomings of the traditional hydraulic control system, this embodiment improves a hydraulic control system suitable for suppressing artillery reference figure 2 , including a first position regulator 1, a PID regulator 2, a servo valve 3, an actuator 4, a data processor 5, a second position regulator 6, a third position regulator 7 and a speed corrector 8; the first The position regulator 1, the PID regulator 2, the servo valve 3 and...

Embodiment 2

[0040] A control method for a hydraulic control system suitable for suppressing artillery, comprising the following steps:

[0041] Step 1: Obtain the angle value of the suppressed gun barrel from the angle encoder, and feed back the angle value to the first position regulator;

[0042] Step 2: using the data processor to perform differential processing on the angle value to obtain the angular velocity of the suppressed gun barrel, and send the angular velocity to the second position regulator;

[0043] Step 3: Obtain the target position of the suppressed artillery barrel, and obtain the position deviation of the suppressed artillery barrel by using the first position regulator, the target position and the angle value;

[0044] Step 4: Calculate and obtain the target speed for suppressing the gun barrel according to the position deviation;

Description

technical field [0001] The invention relates to the technical field of hydraulic servo systems, in particular to a hydraulic control system suitable for suppressing artillery and a control method thereof. Background technique [0002] As the hydraulic servo system is more and more widely used in suppressing artillery, the nonlinearity of the hydraulic control system and the large inertia of the artillery pose new challenges to the control system. However, in actual engineering, due to the limitation of the angular position sensor and its signal acquisition system, the speed obtained by this method is inaccurate, and because of the hysteresis and strong nonlinearity of each link of the hydraulic system, it is easy to cause long dynamic adjustment time. A series of problems such as system instability and speed loop oscillation have increased the difficulty of debugging control parameters. [0003] In view of this, this application is proposed.
