Abstract

The invention relates to a solid vector thruster multi-valve cooperative control method, device and system. The solid vector thruster comprises a plurality of thruster valves, the input ends of the multiple thruster valves share a gas generator channel, and output thrust of the multiple thruster valves is used for achieving aircraft attitude control. The control method comprises the following steps: establishing a linear relation between control forces required by pitching, yawing and rolling channels and valve opening degrees of thruster valves corresponding to the channels, and enabling the sum of the valve opening degrees of the plurality of thruster valves to be a fixed value during working; and the output thrust of the corresponding thruster valve is controlled according to the valve opening degree. The multi-valve synergistic effect is achieved while it is guaranteed that the pressure intensity of the system is stable, and vector thrust is continuously adjustable.

Description

technical field [0001] The invention relates to the technical field of solid attitude control power systems, in particular to a multi-valve cooperative control method, device and system for a solid vector thruster. Background technique [0002] The gas generated by solid propellant is used as the working medium, which has the advantages of small size, atmospheric storage, maintenance-free, etc. It has high pressure and large thrust, and can realize the large attitude orbit change of the aircraft under the same space structure mode. However, the combustion of solid propellant cannot be regulated, and the change of each valve of the thruster will cause huge fluctuations in system pressure, which can easily lead to system structure damage, excessive thrust performance deviation, and the system cannot work normally. SUMMARY OF THE INVENTION [0003] The embodiments of the present invention provide a multi-valve cooperative control method, device and system for a solid vector t...
