A phase-locked phase filter for the minitrack system
(National Aeronautics and Space Administration, 1962-09)
A variable-bandwidth filter has been designed and built to narrow the postdetection bandwidth of the Minitrack satellite tracking system. It is based on phase-lock techniques. Al its narrowest bandwidth, 0.03 cps, the phase ...
Trajectory tracking of underactuated surface vessels: a linear algebra approach
(Institute of Electrical and Electronics Engineers, 2013-07)
This brief presents the design of a controller that allows an underactuated vessel to track a reference trajectory in the x−y plane. A trajectory tracking controller designed originally for robotic systems is applied for ...
COMPARATIVE ANALYSIS OF CURRENT AND VOLTAGE-CONTROLLED PHOTOVOLTAIC MAXIMUM POWER POINT TRACKING
(Ieee, 2011-01-01)
Maximum Power Point tracking (MPPT) in photovoltaic (PV) systems may be achieved by controlling either the voltage or current of the PV device. There is no consensus in the technical literature about how is the best choice. ...
Comparative analysis of current and voltage-controlled photovoltaic Maximum Power Point tracking
(2011-12-28)
Maximum Power Point tracking (MPPT) in photovoltaic (PV) systems may be achieved by controlling either the voltage or current of the PV device. There is no consensus in the technical literature about how is the best choice. ...
Tracking of radio stars with the minitrack system
(1963-07)
This report will discuss the possibilities of using the Minitack system with a wider predetection Bandwidth in conjunction with the Narrow Band Tracking Filter for the tracking of Radio Stars.
Phase measurement/display subsystem for the Apollo re-entry tracking system
(NASA, 1963-12-13)
A combined system consisting of an Interferometer and a Range System has been proposed (Reference #1) for tracking the Apollo spacecraft during the re-entry phase. The system herein discussed processes the output of the ...
Linear algebra and optimization based controller design for trajectory tracking of typical chemical process
(Planta Piloto de Ingeniería Química, 2014-12)
This paper presents a new controller design to tracking trajectory of a typical chemical process. The plant model is represented by numerical methods and, from this approach, the control actions for an optimal operation ...
Tracking Control Design in Nonlinear Multivariable Systems: Robotic Applications
(Hindawi Publishing Corporation, 2019-08)
In this work, a controller design technique called linear algebra based controller (LABC) is presented. The controller is obtained following a systematic procedure that is summarized in this work. In addition, the influence ...
Stabilization and tracking for P/PI combustion control over a communication channel
(IFAC-PapersOnLine, 2020)
Trajectory-tracking controller design with constraints in the control signals: a case study in mobile robots
(Cambridge University Press, 2014-05)
This paper is a continuation of a previous work of the authors, Scaglia et al., 1. A method is presented to choose the controller parameters such that, the values of the control actions do not exceed the maximum allowable ...
