A new method is proposed to implement
gain-scheduled controllers for nonlinear plants. Given a
family of linear feedback controllers designed for linearizations
of a nonlinear plant about constant operating points, a
nonlinear gain-scheduled controller is derived that preserves
the input-output properties of the linear closed loop systems
locally, about each equilibrium point. The key procedures in
the proposed method are to provide integral action at the
inputs to the plant and differentiate some of the measured
outputs before they are fed back to the scheduled controller.
For a fairly general class of systems, the nonlinear
gain-scheduled controllers are easy to obtain, and their
structure is similar to that of the original linear controllers.
