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.
