An approach for the design of controllers for active suppression of helicopter vibration that combines recent developments in the design of fixed-order dynamic compensators with the frequency-shaped cost functional approach is presented. A robust compensator that provides loop shaping at the plant input is used in conjunction with frequency-shaped cost functionals to arrive at a controller for vibration reduction. The effectiveness of this technique is demonstrated by a detailed case study for the design of an active vibration controller.
