Embodiment Construction

[0080] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0081] like figure 1 As shown, this embodiment includes a launch platform controller 02, a proportional multi-way valve controller 03 and a state sensor group 04 connected to the main control computer 01 through the CAN bus, wherein:

[0082] The main control computer 01 is used to issue specific command information;

[0083] The launch platform controller 02 is used to convert the command information into the work step control output of the corresponding control process, and correct the work step control output according to the received action state of the launch platform fed back by each sensor;

[0084] The proportional multi-way valve controller 03 is used to receive the step control output, activate the corresponding controlled proportional multi-way valve, output the driving signal, control the corresponding hydraulic actuator, and exec...

Abstract

The invention discloses a high-precision high-reliability low-load launch vehicle control system, which comprises a launch platform controller connected with a main control computer via a CAN bus, a proportional multi-way valve controller and a state sensor group. Through a section iterative control strategy and building of a handshake mechanism, normal functions of the system can be ensured, the reliability and the precision of the system are improved, and a task can be ensured to be completed smoothly. Due to the proportional multi-way valve structure of each cylinder, small control amount can be used for restraining shaking of a rack and overshoot of a turning process, and loss of an erection angle during the turning process can be remedied. The invention also comprises a control method.

Description

technical field [0001] The invention relates to a signal control system and a control method. In particular, it relates to a signal control system and a control method for the dynamic stability of a bottom load launch platform. Background technique [0002] Compared with the previous launch vehicle, the low-load launch vehicle is small in size and light in weight, and the launch platform is easy to shake, but the requirements for control accuracy are very high. [0003] Moreover, the traditional launch platform generally adopts the launch method of a fixed platform. The manpower and material support required by this launch method are relatively complicated, and the mobility is poor, the accuracy of the launch positioning angle is low, the response speed is slow, and the operation is complicated. [0004] In this context, it is necessary to design a control system for the launch vehicle, which can effectively solve the problems such as the shaking of the launch platform, mee...
