The problem of active fault-tolerant control (FTC) with multiple performance constraints including the closed-loop stability, the control input and system state constraints, and the optimized quadratic performance as well, is investigated for a class of discrete time-varying systems subject to sensor faults.
The Dual methodology, Active Queue Management (AQM), can be divided into two main categories including the closed-loop control and the open-loop control depending on whether the algorithm uses feedback information.
In addition, during the entire CRC stay including the closed-loop control, carbohydrate was administered in advance of any incipient hypoglycemia.
The emulated inertia is included in the closed loop controllers as the gain of a proportional transfer function, which can virtually have any value.
These types of anti-windup compensators are typically designed to recover performance in the face of windup but can result in loss of performance (including stability) for the closed loop in the face of uncertainty.
A complete model for the system is constructed which includes the closed circulation loop of the flow of deuterium driven solely by buoyancy through the moderator cell, heat exchanger and two interconnecting pipes.
An extensive analysis includes the evaluation of margins for the closed loop shape control action.
In this work, desired metrics for the closed loop system include robust performance, minimization of the closed loop system integral of squared error (ISE) and limiting the maximum controller outputs over the full operating range.
A proof of asymptotic output tracking of the controlled variables is provided for the closed loop feedback linearized system, including proofs of the behaviour of the complex internal dynamics.
The closed loop architecture was developed by using a real-time optimization algorithm, which included the actuators controller as inner loop.
The closed loop layout problem (CLLP) is an FLP that employs a closed loop guided configuration.
