Antenna control and optimization

Proceedings of the IEEE, 1991
A class of radiation problems is considered where an arbitrary smooth surface on which currents may be induced is treated as an antenna. A variety of measures of antenna performance is defined in terms of functionals of the radiation pattern. These in turn give rise to a class of optimization problems in which the current distribution is sought which ...

Optimal Control of Photoisomerization

Physical Review Letters, 2005
We report on optimal control of the photoisomerization of 3,3-diethyl-2,2-thiacyanine iodide dissolved in methanol. Enhancement and reduction of the relative yield of cis to trans isomers are achieved; i.e., the quantum efficiency of the photoisomerization is controlled with optimally phase and amplitude shaped 400 nm femtosecond laser pulses.

Optimized joystick controller

The 26th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005
The purpose of the study was to develop an optimized joystick control interface for electric powered wheelchairs and thus provide safe and effective control of electric powered wheelchairs to people with severe physical disabilities. The interface enables clinicians to tune joystick parameters for each individual subject through selecting templates ...

An Optimally Controlled Respirator

IEEE Transactions on Biomedical Engineering, 1971
An optimally controlled respirator was developed. It has three main features: 1) ventilation is controlled by the patient's metabolic rate from continuously measured C0 2 output, 2) physiologic dead space approximated as a linear function of tidal volume is used to estimate alveolar ventilation, and 3) respiratory rate is computed to minimize ...

Distributed Optimization for Control

Annual Review of Control, Robotics, and Autonomous Systems, 2018
Advances in wired and wireless technology have necessitated the development of theory, models, and tools to cope with the new challenges posed by large-scale control and optimization problems over networks. The classical optimization methodology works under the premise that all problem data are available to a central entity (a computing agent or node).

Optimal controllers are fragile

Proceedings of the 2003 American Control Conference, 2003., 2004
Optimal controllers are structurally unstable. The instability is intrinsic because of constrained optimization. This kind of instability is sometimes identified with "fragility" in the control literature. The fragility is related to hidden degeneracies in the polynomials and matrices of the optimized systems, and may detected by looking for certain ...
