The paper deals with the L1 -optimization concept advanced in the modern control theory withan application to the design of the L1 -optimal lateral autopilot. The control aim is to maintain the desiredroll orientation of an UAV in the presence of external unmeasurable disturbances, in particular, ofa gust. To achieve a high performance index, the two separate control algorithms are proposed. The firstalgorithm is designed in order to implement the L1 -optimal PI control for the stabilization of a given rollvelocity. The second algorithm ensures the L1 -optimal P control necessary to stabilize the roll of the aircraft.Results of a simulation example are given to illustrate the properties of the control method
