Control hierarchy

(wiki-TODO: separate out generalized article)

Overview

There are three hierarchies. The virtual design levels need to be mapped to the physically computing control levels which then need to be mapped to the physically producing assembly levels.

• design levels -> control levels -> assembly levels

This gives an extremely big design space.

Design levels

Starting with very high level programming languages going down a decompression chain to low level signals.

• high language 1: functional, logical, connection to computer algebra system
• high language 2: imperative, functional
• constructive solid geometry graph (CSG graph), parametric surfaces
• quadric nets C¹ – (quadriculation?)
• triangle nets C⁰ – triangulation
• tool-paths
• Primitive signals: step-signals, rail-switch-states, clutch-states, ...

Note that there is a second target for the decompression chain. In the development process. Virtual visualizations are necessary.

Control levels

• central computer
• semi local nano-electronics
• local nano-mechanics

Assembly Levels

The physical assembly process. Main article: Assembly levels
