“…Classical design of FCS laws relies heavily on engineering skills and experience of the designers [2,3,4].There are also many modern control design methods to solve the multi-objective problem of autoland control. Some scholars adopted H∞, H2, LQG/LTR control technique to design autoland system encountering windshear [5,6], but researches above just focused on the theory, which do not fit the engineering requirements of CAT III landing.…”
