The design of a multivariable control system for gust alleviation is demonstrated. The use of computers for control design, summarized under the name computer aided design, is described. The gust control system for gust alleviation is integrated into an overall flight guidance control system. Two control designs, using optimal control laws, are achieved, one with complete and the second with incomplete state measurement. In the model description the elastic behavior of the wing is included, as well as the non-steady aerodynamic lift generation and the dynamic behavior of the actuators. The efficiency of gust alleviation is shown in a flight through turbulent air for a STOL-transport aircraft. The increase of wing lifetime and the corresponding decrease in structure weight by use of a gust alleviation system is calculated. (Author)
