Flight Control Applications of 1 sub 1 Optimization,

Abstract

The l sub 1 optimization method is used to handle tracking issues in the design of discrete flight controllers for a SISO aircraft longitudinal control problem. The l sub 1 optimization approach is discussed theoretically and on a broad conceptual level. Constraints are developed to handle control deflection and rate limitations, overshoot and undershoot limitations and steady state error requirements. The effect of each constraint is evaluated with simulations of the aircraft model. A closed loop model-matching design is also presented which produces acceptable tracking results with a lower order controller.
