The method includes the steps that firstly, the arrangement numbers and the assembling positions of sensors, stepping motors, stepping motor drivers, non-self-locking limiting switches, power sources of the non-self-locking limiting switches and motor reducer combinations are determined according to a structural drawing of the vibration isolation control system of the flexible buoyant raft; secondly, the models of the sensors, the stepping motors, the stepping motor drivers, the motor reducer combinations, the non-self-locking limiting switches and the power sources of the non-self-locking limiting switches are selected; thirdly, the sensors, the stepping motors, the stepping motor drivers, drive power sources, the motor reducer combinations, the non-self-locking limiting switches, the power sources of the non-self-locking limiting switches and a Dspace are connected with wires and installed; fourthly, a MATLAB / Simulink control algorithm is designed and related channels are arranged; and fifthly, the MATLAB / Simulink control algorithm is downloaded to Dspace hardware, and online operation and monitoring are performed. The problems that control overflow and observation overflow are likely to happen and an intelligent controller is difficult to design in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of vibration isolation systems, in particular to a design method for a flexible floating raft intelligent vibration isolation control system. Background technique [0002] The acoustic stealth ability of a submarine is one of the important factors related to its vitality and combat effectiveness, so reducing the vibration and noise level of a submarine is a very important task. Floating raft is a kind of vibration and noise reduction equipment widely used in submarines in various countries. It can significantly reduce the transmission of high-frequency vibration of equipment in the boat to the hull. It's not ideal. At present, the known dynamic modeling methods of floating raft vibration isolation systems mainly include multi-rigid body dynamic modeling methods, finite element dynamic modeling methods, impedance comprehensive modeling and analysis methods, modal impedance comprehensive modeling and analysis...
