Instability Condition Derivation for Hydraulic AGC System under Pressure Closed-Loop Control

Model-Based Closed-Loop Control of the Hydraulic Fracturing Process

Closed Loop Pressure Control for the Extrusion Process

Extrusion is a continuous process and successful economic production depends on maintaining stable output and melt quality at an accurately controlled rate. Current screw design technology, the use of DC drives, computerized controllers and raw material testing help to deliver the melt to the extrusion die at relatively constant temperature, pressure and viscosity. However, even the slightest v...

Motor / Tachometer Closed - Loop Speed Control System

Crowdsourcing for closed-loop control

We present a system for large scale robotic learning from demonstration. We describe a set of software tools for enabling human-robot interaction over the internet and gathering the large datasets that such crowdsourcing makes possible. We show results in which humans teach a robot to navigate a maze over the Internet. Robots occupy a peculiar place in our culture. We have been building robots ...

A Closed-Loop Adaptive System for Command and Control

On Navy ships, technological developments enable crews to work more efficiently and effectively. However, in such complex, autonomous, and information-rich environments a competition for the users’ attention is going on between different information items, possibly leading to a cognitive overload. This overload originates in the limitations of human attention and constitutes a well-known and we...
