This chapter mainly concerns with how a general nonlinear system can be controlled adaptively. It considers the various robust adaptive methods, especially in possible application in aeroservoelastic design. While integral control lies at the heart of any adaptation method (e.g. model‐reference control, integral backstepping control, autoregressive identification), the time integration involves a nonlinear function of both unknown parameters and input, output or state variables. The chapter explores how such a method can be simply but effectively applied to an uncertain systems with an unknown structural nonlinearity superimposed over a basic linearized system. The model reference adaptation systems (MRASs) adaptive control procedure can be applied to robust control in the presence of bounded random disturbance inputs. Application of model‐reference adaptation to a 3‐D wing is much more cumbersome than that for a typical section, primarily due to the large number of degrees of freedom involved.
