The gain scheduling of a multivariable controller designed using Hinfinity optimization is presented. The design uses a two-degree-of-freedom Hinfinity optimization based on five linearizations taken from the non-linear rigid body equations of motion of a helicopter over the range 0-80 knots. A scheduled multivariable controller has been implemented making use of a multivariable state estimator/state estimate feedback structure. The controller's parameters were computed on-line by linear interpolation with air speed of the design parameter sets. The interpolation scheme appeared stable in extensive simulations. The resulting controller schedule was tested using a sophisticated and representative non-linear simulation.
