A Sensorless Inverse Optimal Control Plus Integral Action to Regulate the Output Voltage in a Boost Converter Supplying an Unknown DC Load
(Institute of Electrical and Electronics Engineers Inc., 2023)
This study utilizes inverse optimal control (IOC) theory to address the issue of output voltage regulation in a boost converter feeding an unknown direct current (DC) load. The proposed approach involves developing a general ...
Sensorless Adaptive Voltage Control for Classical DC-DC Converters Feeding Unknown Loads: A Generalized PI Passivity-Based Approach
(Cartagena de Indias, 2021-09-24)
The problem of voltage regulation in unknown constant resistive loads is addressed in this paper from the nonlinear control point of view for second-order DC-DC converters. The converters’ topologies analyzed are: (i) buck ...
Mechanical Sensorless Speed Control of Permanent Magnet Motors Driving an Unknown Load
(Institute of Electrical and Electronics Engineers, 2006-04)
A new sensorless scheme for high-performance speed control of permanent-magnet ac motors (PMACMs) driving an unknown load is proposed. This scheme uses an extended nonlinear reduced-order observer to estimate the induced ...
Nonlinear Control of a Buck Converter Which Feeds a Constant Power Load
(Institute Of Electrical And Electronics Engineers, 2015-12)
In this paper a non-linear control strategy for controlling a dc/dc Buck converter feeding a constant power load is proposed. The main objective of the proposed controller is to improve the transient performance when in ...
Voltage regulation of an isolated DC microgrid with a constant power load: a passivity-based control design
(Cartagena de Indias, 2021-08-28)
Passivity-based nonlinear control for an isolated microgrid system is proposed in this paper. The microgrid consists of a photovoltaic array and a battery energy storage connected to a point of common converters, supplying ...
Adaptive Sensorless PI+Passivity-Based Control of a Boost Converter Supplying an Unknown CPL
(Cartagena de Indias, 2022)
This paper presents an adaptive control to stabilize the output voltage of a DC–DC boost converter that feeds an unknown constant power load (CPL). The proposed controller employs passivity-based control (PBC), which assigns ...
Fast Adaptive Trajectory Tracking Control for a Completely Uncertain DC Motor via Output Feedback
(Revista Computación y Sistemas; Vol. 12 No.4, 2009-05-15)
Abstract. An algebraic parameter identification method, developed for fast, on-line, computation of unknown linear system parameters, is here used for the fast adaptive output feedback control of a completely unknown dc ...
A Global Tracking Sensorless Adaptive PI-PBC Design for Output Voltage Regulation in a Boost Converter Feeding a DC Microgrid
(Cartagena de IndiasCampus Tecnológico, 2023-01-19)
The problem of the output voltage regulation in a DC-DC boost converter feeding a DC microgrid is addressed in this research via the passivity-based control theory with a proportional–integral action (PI-PBC). Two external ...
Meagre effects of disuse on the human fibula are not explained by bone size or geometry
(Springer London Ltd, 2017-02)
Summary: Fibula response to disuse is unknown; we assessed fibula bone in spinal cord injury (SCI) patients and able-bodied counterparts. Group differences were smaller than in the neighbouring tibia which could not be ...
