Abstract
We describe the design and testing of longitudinal and lateral controllers for the Bell 205 helicopter. The controllers were designed using H∞ optimization in conjunction with low-order linearization taken from a nonlinear flight mechanic model. During flight-tests, decoupled responses were obtained, and desired handling qualities achieved. Tuning the design parameters to bring about desired changes in performance was straight-forward. The bandwidths achieved in flight were close to those predicted by linear analysis
