LPV Modeling for Control Scheme Design of a Compound Helicopter

Résumé

The compound helicopter is able to reach speeds that significantly surpass the conventional counterpart. However, the compounding of lift and thrust always results in more complicated aerodynamic and control issues than a conventional helicopter. Therefore, it is important to model and evaluate the flight dynamics in the early design phase of a compound configuration. The aim of this paper is to develop a Linear-Parameter-Varying (LPV) model of a compound helicopter and investigate the trim, stability and control characteristics. A series of discrete linear state-space models and trim data are obtained from the nonlinear mathematic model, and then interpolated for construction of a LPV model with respect to two scheduling parameters. Lastly, the LPV model is augmented with control scheme to perform flight simulation covering the speed envelope.
