Fig. 4 shows the block diagram of a system in which the microprocessor’s role has been expanded to control and coordinate the functional relationships between the motion requirements, machine ...

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

If you look at the block diagram on this page, you'll see there are five elements of an observer: the two inputs - the actual sensor output (Y) and the power converter output (plant excitation) PC - ...

Closed-loop control allows single-phase ac motors to close the gap in performance and efficiency that exists between these motors and other higher-performance, higher-cost motors.

Closed Loop MRP (Manufacturing Resource Planning) is a computerized system used for production planning and inventory control.

A closed-loop system of insulin delivery (also called an artificial pancreas) may improve glycemic outcomes in children with type 1 diabetes.

Conclusions A hybrid closed-loop system significantly improved glycemic control in very young children with type 1 diabetes, without increasing the time spent in hypoglycemia.
