Performance Analysis And Improvement In Model Reference Adaptive Control
(1994)Boundedness of all closed-loop signals and asymptotic convergence of the tracking error to zero or to a residual set are the criteria that have been most commonly used to characterize the performance of model reference ...

Performance improvement versus robust stability in model reference adaptive control
(Publ by IEEE, 1992)The mean square tracking error criterion and the L∞ tracking error bound criterion are used to assess the performance of a standard robust model reference adaptive control schemes in ideal and nonideal situations. Controller ...

Redox chemistry of sulphate and uranium in a phosphogypsum tailings dump
(2010)The present study aims to assess the effect of redox conditions existing within the tailings dump on the stability of phosphogypsum (e.g. sulphate reduction) and uranium(VI). Phosphogypsum sampling and in-situ measurements ...

Robust adaptive control for a class of mimo nonlinear systems
(2002)The design of stabilizing controllers for nonlinear plants with unknown nonlinearities is a challenging problem. The inability to identify the nonlinearities on-line or off-line accurately motivates the design of stabilizing ...

Robust adaptive control of minimum phase non-linear systems
(1996)We show that an adaptive input/output feedback linearization control scheme for minimum phase nonlinear systems is robust with respect to unstructured plant uncertainties such as unmodelled dynamics and disturbances provided ...

A robust adaptive nonlinear control design
(1996)An adaptive control design procedure for a class of nonlinear systems with both parametric uncertainty and unknown nonlinearities is presented. The unknown nonlinearities lie within some 'bounding functions', which are ...

Robust adaptive sliding control of linearizable systems
(2001)A switching adaptive control algorithm based on a sliding mode method is proposed for a class of single-input, single-output nonlinear systems with unknown dynamics. The plant is assumed to be linear-in-the-control input ...

Robustness of nonlinear control systems with respect to unmodeled dynamics
(1996)In this paper, we examine the global stability properties of nonlinear controllers in the presence of high frequency unmodeled dynamics. We develop necessary and sufficient conditions for a general class of nonlinear control ...

Stability and performance of nonlinear robust adaptive control
(IEEE, 1995)Recently, a new class of adaptive control schemes, motivated from nonlinear systems theory, has been proposed for minimum phase linear time invariant plants. Under certain assumptions on the plant transfer function, these ...

Stable indirect adaptive control of continuous-time systems with no a priori knowledge on the parameters
(Publ by Pergamon Press Inc, 1993)A crucial drawback of indirect adaptive control is the stabilizability or controllability of the estimated plant model which is required in order to calculate the controller parameters. Loss of stabilizability at a particular ...

A stable indirect adaptive control scheme for first-order plants with no prior knowledge on the parameters
(Publ by IEEE, 1991)An indirect adaptive control scheme for a first-order linear time-invariant plant with unknown parameters is presented and analyzed. The scheme requires no prior knowledge about the sign or bounds of the plant parameters. ...

Using the milliken moment method and dynamic simulation to evaluate vehicle stability and controllability
(American Society of Mechanical Engineers (ASME), 2004)The Milliken Moment Method (MMM) is a way of efficiently organizing the results from a kinematically constrained vehicle test. Using the MMM and closed-loop dynamic simulation, the authors present a new method for evaluating ...
