| description | To improve the output accuracy of strap-down inertial measurement unit which is in compound dynamic environment of missile which has a high acceleration, strong impact, and high vibration, an adaptive damping method of taking the magneto rheological elastomer as the vibration damper is designed. This method takes the error between the vibration response of the missile and the dynamic response of SIMU as the performance index of optimal control. By optimal control, the stiffness and damping of the magneto rheological elastomer are automatically adjusted, the vibration response of the SIMU is controlled, and the output accuracy of SIMU is improved. Results of experiments show that the method solves the problem that the stiffness and damping of the SIMU damping system could not be changed in real time to adapt to the dynamic environment, and there is almost no time delay and this has an obvious damping effect. |
