Controlling Cotton Card Sliver Unevenness with Sampled-Data Control Having Prop rtional Action Part 4

Sampled-data supervisory control

This paper focuses on issues related to implementing timed discrete-event systems (TDES) supervisors, and the concurrency and timing delay issues involved. In particular, we examine issues related to implementing TDES as sampled-data (SD) controllers. An SD controller is driven by a periodic clock and sees the system as a series of inputs and outputs. On each clock edge (tick event), it samples...

Optimal Sampled-data Control

Bios Data Analysis. Part 4. Flux and Action: Process Statistics

New methods for time series analysis describe patterns of variation and thereby identify creative phenomena. Regarding variation as meaningful change rather than meaningless variability, process statistics (1) analyzes time series; (2) measures changes in statistical parameters; (3) focuses on asymmetry and causality, the properties of directed action; and (4) rejects methodological assumptions...

Controlling aliased dynamics in motion systems? An identification for sampled-data control approach

Sampled-data control systems occasionally exhibit aliased resonance phenomena within the control bandwidth. The aim of this paper is to investigate the aspect of these aliased dynamics with application to a high performance industrial nanopositioning machine. This necessitates a full sampled-data control design approach, since these aliased dynamics endanger both the at-sample performance and t...

Spacing Control and Sliver-free Delaunay Mesh

|We are often required to generate a Delaunay mesh whose element size is within a constant factor of a control spacing function, i.e., well-conformed, in addition to the fact that each mesh element has small aspect ratio, i.e., well-shaped. However, generating wellshaped Delaunay meshes is an open problem for a long time. Observe that slivers have small radius-edge ratio thus the Delaunay trian...
