Concepts, methods and techniques in adaptive control
Adaptive control is the control method used by a controller which must adapt to a controlled system with parameters which vary, or are initially uncertain. For example, as an aircraft flies, its mass will slowly decrease as a result of fuel consumption; a control law is needed that adapts itself to such changing conditions. Adaptive control is different from robust control in that it does not need a priori information about the bounds on these uncertain or time-varying parameters; robust control guarantees that if the changes are within given bounds the control law need not be changed, while adaptive control is concerned with control law changing itself. The foundation of adaptive control is parameter estimation , which is a branch of system identification. Common methods of estimation include recursive least squares and gradient descent. Both of these methods provide update laws which are used to modify estimates in real time i. Lyapunov stability is used to derive these update laws and show convergence criteria typically persistent excitation; relaxation of this condition are studied in Concurrent Learning adaptive control.
Adaptive control is no longer just an important theoretical field of study, but is also providing solutions to real-world problems. Adaptive techniques will transform the world of control. The leading world practitioners of adaptive control have contributed to this handbook which is the most important work yet in this field. Not only are techniques described in theory, but detailed control algorithms are given, making this a practical cookbook of adaptive control for both control professionals and practising engineers. The book presents the most advanced techniques and algorithms of adaptive control. These include various robust techniques, performance enhancement techniques, techniques with less a-priori knowledge, nonlinear adaptive control techniques and intelligent adaptive techniques.

Похоже, кто-то очень нами недоволен, директор. Это шантаж. Больше всего похоже на требование выкупа. Слова Сьюзан прозвучали слабым, едва уловимым шепотом: - Это… Энсей Танкадо.
Сейчас она держалась подчеркнуто сдержанно, и это пугало его еще сильнее. - Так в чем же проблема, Фил? - спросил Стратмор, открывая холодильник. - Может, чего-нибудь выпьешь.
Человек, с которым он вступил в контакт, Северная Дакота, не звонил. Проклятые американцы. Никакого представления о пунктуальности.
Беккер резким движением взял парня под мышки, приподнял и с силой посадил на столик.
