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 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 TECHNIQUES FOR A CLASS OF LARGE-SCALE SYSTEMS.
(IEEE, 1984)The adaptive control of a class of large-scale systems formed of an arbitrary interconnection of subsystems with unknown parameters and bounded disturbances is investigated. New decentralized adaptive controllers are ...

Adaptive stabilization of not necessarily minimum phase plants
(1986)We show that a first-order adaptive regulator can stabilize any linear time-invariant plant (LTI) whose transfer function has arbitrary relative degree and order, and is not necessarily minimum phase, provided the dominant ...

APPLICATION OF ROBUST DIRECT ADAPTIVE CONTROL TO THE LONGITUDINAL DYNAMICS OF A FIGHTER AIRCRAFT.
(IEEE, 1986)The authors investigate the use of a robust direct adaptive controller (RDAC) for controlling the linearized time-varying dynamics of the longitudinal motion of an F-16 aircraft and compare its performance with that of ...

An Asymptotic Error Analysis of Identifiers and Adaptive Observers in the Presence of Parasitics
(1982)The behavior of identifiers and adaptive observers in the presence of parasitics is analyzed. Bounds for the state/parameter error are established. The adaptive schemes considered are shown to be robust provided the input ...

Class of unmodeled dynamics in robust adaptive control.
(Publ by American Automatic Control Council, 1988)The authors use time-domain and frequency-domain bounds to characterize the class of allowable unmodeled dynamics in robust adaptive control. This class is a general one and includes time delays, distributed systems, etc. ...

Article
Decentralized Adaptive Control of Interconnected Systems
(1986)The adaptive control of a class of large-scale systems formed of an arbitrary interconnection of subsystems with unknown parameters, nonlinearities, and bounded disturbances is investigated. It is first shown that no matter ...

Decentralized adaptive control of interconnected systems with reduced-order models
(1985)The adaptive control of interconnected systems whose subsystems possess slow and fast modes is investigated in the presence of external disturbances. A simple example is first used to show that a decentralized adaptive ...

GENERAL ROBUST ADAPTIVE LAW FOR TUNING CONTROLLERS.
(IEEE, 1986)A general robust adaptive law is developed which can stably tune model-reference and pole-placement control schemes despite the presence of unmodeled dynamics and bounded disturbances. The analysis shows that a switching- ...

Article
Instability analysis and improvement of robustness of adaptive control
(1984)The effects of unmodeled high frequency dynamics and bounded disturbances on stability and performance of adaptive control schemes are analyzed. Five possible types of instability mechanisms-parameter drift, 'linear' ...

ON THE MODEL REFERENCE ADAPTIVE CONTROL OF TIME-VARYING PLANTS.
(IEEE, 1987)The authors have studied the problem of developing an adaptive control law that can force the output of a linear time-varying plant to track the output of a linear time-varying reference model and at the same time guarantee ...

Parameter estimation and pole-placement control of time-varying plants.
(Publ by American Automatic Control Council, 1988)The pole placement and adaptive pole placement control problem of linear time-varying plants with smooth parameters is considered. A controller structure is proposed which guarantees the closed-loop stability and meets the ...

ROBUST ADAPTIVE CONTROL.
(IEEE, 1984)This paper considers the robust redesign of a direct adaptive controller applied to a linear time invariant plant with unmodeled stable dynamics. In order to achieve robustness the adaptive law is modified by retarding the ...
