Abstract
A typical approach to control of a nonlinear system is to linearize the system about a nominal operating point. Then linear feedback design methods are used, yielding a closed-loop system whose linearization about the corresponding closed-loop operating point has the desired characteristics. Recently the authors have been developing a systematic analytical reformulation called design by extended linearization. The nonlinear system to be controlled is assumed to have a continuous family of constant operating points, and the design procedure is based on the corresponding continuous linearization family. Applying linear control techniques to this family of linear systems yields a continuous family of linear feedback control laws for a specified objective. Thus the family of linearized closed-loop systems has the desired behavior. Simulations of the F-8C aircraft using a nonlinear controller and comparisons with simulations using a standard linear controller are presented.
