Abstract:
A multi-objective coordinated attitude control method was studied, which is aimed at the high precision attitude control of the dual layer air spring vibration isolation mounting. After establishing the dynamics model of dual layer air spring vibration isolation mounting and the equivalent model of charge and discharge control, the control response characteristic model was established. Then the multi-objective coordinated attitude control model was brought out based on the multi-objective satisfactory optimization method. This control method can adapt to the attitude control coupling of the superstratum and the substratum air spring vibration isolation mounting. And it can also restrain the elasticity distortion influence on the attitude equilibrium control. This control method was verified on a dual layer air spring vibration isolation mounting experimental system. It can be used in a dual air spring vibration isolation mounting for some large ship generator set and can realize the high vibration isolation efficiency.
