AATS for the X̄ Chart with Variable Parameters
(1999-10-01)
A Fortran computer program is given for the computation of the adjusted average time to signal, or AATS, for adaptive X̄ charts with one, two, or all three design parameters variable: the sample size, n, the sampling ...
A hierarchy of adaptive (X)over-bar control charts
(Elsevier B.V., 2009-06-01)
The purpose of this article is to present a statistical design of a hierarchy of two-states adaptive parameters (X) over bar charts. We assume that the shift in the process mean does not occur at the beginning of the ...
Mitigation of symmetry condition in positive realness for adaptive control
(Elsevier B.V., 2006-09-01)
Feasibility of nonlinear and adaptive control methodologies in multivariable linear time-invariant systems with state-space realization (A, B, C) is apparently limited by the standard strictly positive realness conditions ...
Frequency-Adaptive Current Controller for Three-Phase Grid-Connected Converters
(Institute Of Electrical And Electronics Engineers, 2013-10)
This paper analyzes the behavior of a nonfrequencyadaptive reduced-order-generalized-integrator-based current controller when the grid frequency is subject to variations and proposes a simple method for making it frequency ...
Combining fractional order operators and adaptive passivity-based controllers: an application to the level regulation of a conical tank
(Romanian Society of Control Engineering and Technical Informatics, 2017)
In this paper, fractional order (FO) operators and adaptive passivity-based controllers (APBC) are combined. The main aim is to explore possible advantages of combining FO operators and APBC over the use of integer order ...
Self-adaptive Software: Development Approach and Automatic Process for Adaptation at Runtime
(Univ Passo Fundo, 2015-04-01)
The development of Self-adaptive Software (SaS) is a complex task, since this type of software constantly deals with structural and/or behavioral changes at runtime so that the needs of its users or its execution environment ...
Discrete-time sliding mode neuro-adaptive controller for SCARA robot arm
(Springer, 2017-12)
This work presents a discrete-time sliding mode neuro-adaptive control (DTSMNAC) method for robot manipulators. Due to the dynamics variations and uncertainties in the robot model, the trajectory tracking of robot manipulators ...
Adaptive control charts: A Markovian approach for processes subject to independent disturbances
(Elsevier B.V., 2006-01-01)
Recent studies have shown that adaptive X control charts are quicker than traditional X charts in detecting small to moderate shifts in a process. In this article, we propose a joint statistical design of adaptive X and R ...
