AAA Note on the Behaviour of Nonparametric Density and Spectral Density Estimators at Zero Points of their Support
(2015)The asymptotic behaviour of nonparametric estimators of the stationary density and of the spectral density function of a stationary process have been studied in some detail in the last 50-60years. Nevertheless, less is ...

Absolutely monotonic functions related to Euler's gamma function and Barnes' double and triple gamma function
(2011)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 ...

Accomodation of failures in the flight control system of the F-16 aircraft using adaptive control
(Publ by American Automatic Control Council, 1990)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, ...

Adaptive bandwidth choice
(2003)In this paper, we consider the problem of bandwidth choice in the parallel settings of nonparametric kernel smoothed spectra] density and probability density estimation. We propose a new class of 'plug-in' type bandwidth ...

Adaptive control design for cargo ship steering with limited rudder angle
(2009)Marine transportation offers a cost-effective and viable alternative to cargo aircraft, trains, and trucks in general. Traffic control in congested waterways has recently become a challenging task demanding higher accuracy ...

Adaptive control for a class of large scale non-linear systems
(2005)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 ...

Adaptive control of a class of slowly time varying systems with modeling uncertainties
(2005)In a recent work, a new linear adaptive controller based on certainty-equivalence and backstepping design, which promises a level of transient and asymptotic performance comparable to that of the tuning functions adaptive ...

Adaptive control of an aeroelastic airbreathing hypersonic cruise vehicle
(2007)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 ...

ADAPTIVE CONTROL OF LARGE SCALE SYSTEMS WITH REDUCED MODELS.
(Springer-Verlag, 1985)This paper considers the robust redesign of decentralized adaptive controllers for a class of large scale systems formed of an arbitrary interconnection of subsystems with unknown parameters. In the design, a lower order ...

Adaptive control of linear time varying systems
(1996)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 ...

Adaptive control of linear time-varying plants
(1987)In this paper the model reference adaptive control (MRAC) problem of a class of linear time-varying (LTV) plants is considered. The plant parameters are assumed to be smooth, bounded functions of time which satisfy the ...

ADAPTIVE CONTROL OF LINEAR TIME-VARYING PLANTS: A NEW CONTROLLER STRUCTURE.
(American Automatic Control Council, 1987)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 ...

Adaptive Control of Linear Time-Varying Plants: A New Model Reference Controller Structure
(1989)In this paper we study the problem of developing a control law which can force the output of a linear time-varying plant to track the output of a stable linear time-invariant reference model. We first show that the standard ...

Adaptive control of Networked Distributed Systems with unknown interconnections
(Institute of Electrical and Electronics Engineers Inc., 2016)Networked Distributed Control Systems (NDCS) consist of a number of interacting subsystems and usually face the challenge of delays induced by the communication network. In this paper we consider the case where each subsystem ...

Adaptive control of time‐varying plants: Simple examples
(1988)The design and properties of an adaptive model reference scheme and an adaptive pole placement control scheme for linear time‐varying plants are demonstrated via two simple examples. The two new schemes combine new control ...

Adaptive control of unmanned aerial vehicles in atmospheric flight with reduced models
(2007)We propose an approximate implementation scheme for an adaptive linear quadratic control structure by employing a balanced truncation procedure in the loop prior to solving the associated Algebraic Riccati Equation (ARE). ...

Adaptive disturbance rejection for disk drives using neural networks
(2008)This paper presents the experimental verification of an adaptive feedforward disturbance rejection scheme for hard disk drives. The control scheme is shown to reduce the error during track-following by as much as 11.8%. ...
