Abstract

This paper deals with the design of the l1-optimal digital autopilot needed to control of the rollfor an aircraft under an arbitrary unmeasured disturbances. This autopilot has to achieve a desired lateralmotion control via minimizing the upper bound on the absolute value of the difference between the givenand true roll angles. It is ensured by means of the two digital l1-optimal controllers of PI type. The mainresult consists in establishing the fact that the autopilot can be robust in the presence of parametric andnonparametric uncertainties
