An active vibration control scheme in helicopters is persented, which is based on the concept of ACSR (Active Control of Structural Response). First, using a mathematical procedure employing the Fisher Information Matrix, optimum sensor locations have been identified in a three dimensional model of a flexible fuselage structure. It is observed that irrespective of the excitation frequency, these optimally selected sensor locations experience relatively high levels of vibration. Then, using the measurement from these optimal sensor locations, a MIMO (Multi-Input Multi-Output) control problem has been formulated and solved to obtain the active control forces required for vibration minimization in the helicopter fuselage.
