This paper proposes a vibration attenuation strategy for space borne optical interferometers to meet their submicron positional stability requirements. Specifically, the Stellar Interferometer Mission requires 10-nm level stabilization of optical ele

This paper presents an asymptotic output tracking stability proof for a new modification to a direct model reference adaptive control procedure. This modification, which alleviates a very restrictive positive real constraint, greatly expands the clas

Individuals were trained to modulate their EEGs in order to move a cursor on a video screen to intercept a moving target. EEG activity was recorded from the scalp over the central sulcus of the left hemisphere, and mu-rhythm amplitude was assessed th

This paper presents a new adaptive hierarchical control technique that adjusts its structure in order to maintain good performance over a wide variation of plant operating conditions. In contrast to the conventional approach of designing a compensato

This paper analyzes and extends an easily implemented direct model reference adaptive control procedure. The paper focuses on the major limitation of this control approach which is the satisfaction of a strictly positive real sufficiency condition in

This study began development of a new communication and control modality for individuals with severe motor deficits. We trained normal subjects to use the 8–12 Hz mu rhythm recorded from the scalp over the central sulcus of one hemisphere to move a

Characteristically, the coronary circulation has been studied in the time-honored way of varying a single experimental variable while attempting to hold other hemodynamic variables constant. This has produced two-dimensional descriptions of coronary

The goal of this work is to develop an expert, hierarchical control scheme that adapts its structure in arcordance with a broad range of plant variations and knowledge about the plant. The coarsest control, provided by a fuzzy controller, moves the s

This paper describes an adaptive decoding device designed to develop and evaluate EEG-based communication from the device user to a computer. The decoder transforms EEG activity into cursor movement. The operator, who is considered part of the device
