Abstract

For flexible aircraft, it is often required to control individual aeroelastic modes which are lightly damped or even unstable. In order to achieve a maximum controller performance, a large number of measurements and control surfaces is required, which in turn complicates controller design. Blending control inputs and measurement outputs, individual aeroelastic modes can be isolated efficiently and hence controlled by a single input single output controller. In this paper, a novel approach is presented for designing H2-optimal blending vectors for the control of individual aeroelastic modes. An efficient algorithm is derived to jointly compute the interdependent input and output blending vectors, where an explicit mode decoupling can be considered. The effectiveness of the proposed approach is proven by designing a gust load alleviation system for a flexible aircraft with distributed flaps and measurements.
