We construct a family of simply connected 2-step nilpotent Lie groups of higher rank such that every geodesic lies in a flat. These are as Riemannian manifolds irreducible and arise from real representations of compact Lie ...

It is shown that the remainders in asymptotic expansions of the logarithm of Barnes double and triple gamma function and Euler's gamma function are Laplace transformations of positive multiples of absolutely monotonic ...

The effect of surface and hardware failure on the flight control system of the F-16 fighter aircraft is examined. In the absence of failures and unpredictable changes, the controller, which is based on gains scheduling, ...

This paper considers the design of stable adaptive neural controllers for uncertain nonlinear dynamical systems with unknown nonlinearities. The Lyapunov synthesis approach is used to develop state-feedback adaptive control ...

The design of stabilizing controllers for multi-input multi-output (MIMO) non-linear plants with unknown non-linearities is a challenging problem. The inability to identify the non-linearities on-line or off-line accurately ...

This paper describes an adaptive linear quadratic (ALQ) altitude and velocity tracking control algorithm for the longitudinal model of a generic airbreathing hypersonic flight vehicle. The vehicle design is inspired by a ...

A new class of adaptive controllers for linear time varying systems is designed and analyzed using nonlinear design techniques and the certainty-equivalence approach. It is established that this new class of controllers ...

The model reference control and model reference adaptive control problems are considered for a class of linear time-varying plants with bounded, piecewise smooth parameters. A controller structure that solves the model ...
