Electronic control logic and system components are described that are used with a venturi carburetor to accomplish the fuel metering required in a closed loop emission control system. Special open ...

A closed-loop control system gathers feedback information from sensors and makes appropriate process adjustments at its output, automatically and without human intervention.

In order to accurately control the ignition and fuelling of a gasoline engine, in the presence of environmental and system variability, it is necessary to measure the effect this variability has on ...

Festo introduces its Controlled Pneumatics technology which features digital closed-loop control for applications ranging from welding and gripping to dispensing and pumping.

Eliminating encoders can simplify installation and system maintenance, and often results in less downtime, better control, and higher throughput. Here's how encoderless systems compare with more ...
