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 mathematical model is developed which describes the operation of an A/F control system containing an engine, an exhaust gas oxygen sensor, and a feedback controller. The dependence of model ...

The closed loop fan controller works by comparing desired speed with actual speed and generating a fan command to minimize the difference. In concept, this can be implemented very simply.

With closed-loop control, poor performance typically manifests itself as deviations from set point. By analyzing these deviations, one can determine if they are caused by suboptimal controller tuning ...

Feedback control methods implemented using low-cost microprocessors enable significant gains for single-phase ac motor speed controls.

If you don’t think control systems are everywhere, consider an example we use when talking to school kids: a toilet. A very simple and very common closed loop control system.

The OMDC-MD Series programmable dc speed control features digital closedloop feedback and LED display for dc motors rated to 2 hp.
