Problems solved by technology

Although this scheme can improve the adjustment accuracy of missile attitude adjustment, due to the influence of temperature and other factors in actual use, the above scheme cannot guarantee the adjustment accuracy in environments close to extreme temperatures or in environments with large temperature changes
In this way, the reliable missile attitude adjustment accuracy cannot be satisfied, which in turn affects the strike accuracy and launch success rate

Embodiment Construction

[0026] like figure 1 The structural block diagram of the stand-alone control system of the launch vehicle is shown. The stand-alone control system of the launch vehicle includes a proportional valve stand-alone digital control unit 1 and a proportional valve unit 20, wherein the proportional valve unit 20 drives the missile on the missile launch vehicle to produce erection, aiming and / or positioning action;

[0027] The proportional valve stand-alone digital control unit 1 includes:

[0028] The control module 10 generates a pulse width modulation signal according to the set current target value and the current feedback value;

[0029] The power operational amplifier module 30 increases the power of the pulse width modulation signal to drive the proportional valve module;

[0030] The current closed-loop feedback module 40 processes the actual current output value of the proportional valve module 20 and feeds back the current feedback value to the control module 10 .

Abstract

In order to improve the control precision of a proportion valve of a launching vehicle under the condition of wide temperature range, the invention provides a single-machine control system of the launching vehicle. The single-machine control system comprises a proportion valve stand-alone digital control unit and a proportion valve unit, wherein the proportion valve unit drives missiles on a missile launching vehicle to generate actions of erecting, acquiring and / or positioning, the proportion valve stand-alone digital control unit comprises a control module, a power operational amplifier module and a current closed loop feedback module, the control module is used for generating a pulse width modulation signal according to a set current target value and a current feedback value, the power operational amplifier module is used for improving the power of the pulse width modulation signal so as to drive a proportion valve module, the current closed loop feedback module is used for processing the actual current output value of the proportion valve module and feeding the current feedback value to the control module. By experimental verification, the precision of 0.3% for controlling the proportion valve of the launching vehicle in the wide temperature range of minus 40DEG C to 60DEG C is realized.

Description

technical field [0001] The invention belongs to the field of automatic control, and more specifically relates to a single-machine control system of a launch vehicle with a proportional valve single-machine digital control unit with a wide temperature range and high-precision feedback control. Background technique [0002] The stand-alone product of the launch vehicle control system that meets the requirements of "three modernizations" of informatization, digitalization, and networking is aimed at meeting the functional requirements of strategic and tactical missile launch vehicles for mobile launch control functions, and comprehensively considers various user needs of various types of launch vehicles. The product is designed according to the development idea of ​​productization, and through different configurations of serialized products, it forms a general stand-alone product that meets the needs of different users. [0003] Leveling and erecting (slewing) control is an imp...
