Abstract :
In order to solve the SINS active vibration control, propose a kind of flexible plate used in SINS of intelligent structure matrix of active vibration control method. This method in establishing flexible sheet on the basis of dynamic model, value-based modal analysis of force to extract the necessary space model reduction mode, based on modal force of piezoelectric element determination criterion optimum allocation scheme, effectively reduced the number of sensors/driver and ensure that the optimal modal control. Using ANAYS software intelligent flexible sheet of dynamic response simulation, results show that this method is used to strap down inertial navigation system, the feasibility of active vibration control.
