It is possible to get very good accuracy with servo pneumatics.  A lot depends on the load, changes in the load, the quality of the the components and the desired speeds.  I have a video where I move about a 5 lb load pretty quickly doing point to point moves and a sine wave where the frequency and amplitude change.

Here is an example of what can be done.

This cannot be done using a normal PID controller with just velocity and acceleration feed forwards.

Interesting article, Peter. I recall years ago there was some talk about high-resolution positioning with servopneumatics. Can you get good positioning accuracy with pneumatics and do those systems still exist?

The use of ZNE technology buildings not only reduces cost and creates renewable energy, but it can give a boost to the economy. The implementation and execution will require a workforce, which means the result can be increased employment.
The use of CFD is more profound in automobile design because of the diverse physics involved. It can be used to optimize components for downsizing and reducing the environmental footprint while maintaining or improving operational efficiency.
A Detroit automaker was struggling with a semi-manual, labor-intensive parts receiving process. Workers had enter parts into a spreadsheet manually at a stationary workstation. This stopped the receiving process dead in its tracks. A better system was needed.
Pressure sensors can be used in a wide range of applications. It’s imperative that they’re suited for use in hazardous situations and are fully compliant with one of several protection standards.
