Carrier rocket attitude control method and device, electronic equipment and storage medium

Abstract

The invention relates to a carrier rocket attitude control method, which comprises the following steps of solving a control angle deviation, filtering a program angle deviation according to a filtering algorithm, calculating a filtered control signal according to a designed correction network, obtaining a control instruction delta of a lateral attitude control nozzle, carrying out digital relay characteristic processing on the control instruction, and carrying out digital relay characteristic processing on the control instruction. And meanwhile, on-off control is carried out on the lateral attitude control spray pipe and the grid rudder system. Aiming at a carrier rocket adopting a control scheme of a grid rudder and a lateral attitude control spray pipe, the invention provides an attitude control system design method adopting grid rudder and lateral attitude control spray pipe compound control in an initial rocket launching section, so that the requirement on attitude control torque can be effectively reduced, the rocket attitude fuel consumption is reduced, the carrier rocket performance is improved, and the carrier rocket performance is improved. And the method has high engineering application value.

Description

technical field [0001] The invention belongs to the technical field of rocket control, and specifically relates to a method, device, electronic equipment and storage medium for attitude control of a launch vehicle. Background technique [0002] Reducing the cost of rockets and improving the carrying capacity of launch vehicles are the main technical issues considered in the design of commercial launch vehicles. Usually, the atmosphere of most small launch vehicles is controlled by grid rudders. The cost of the grid rudder control mechanism is low and the control precision is high; It is necessary to use the lateral attitude control nozzle for attitude control to meet the control requirements of the launch vehicle at low speed. When the lateral attitude control nozzle is mainly used for the attitude control of the launch vehicle outside the atmosphere, the control torque required is small, which has advantages; Torque demand, the required attitude control torque, is far gre...

Problems solved by technology

Usually, the atmosphere of most small launch vehicles is controlled by grid rudders. The cost of the grid rudder control mechanism is low and the control precision is high; It is necessary to use the lateral attitude control nozzle for attitude control to meet the control requirements of the launch vehicle at low speed

When the lateral attitude control nozzle is mainly used for the attitude control of the launch vehicle outside the atmosphere, the control torque required is small, which has advantages; Torque demand, the required attitude control torque, is far greater than the control torque demand of the rocket during the flight outside the atmosphere after separation. Excessive attitude control torque will increase the difficulty of designing the attitude control system of the launch vehicle outside the atmosphere and reduce the performance of the attitude control system. performance, this design challenge needs to be solved urgently
