They are a classical feedback controller where the control gains are set using a table based on the plant system order and normalized natural frequency.

Consider implementing with a microcontroller chip a simple feedback controller:

They also described an early feedback controller for fluids.

This kind of controller is a closed-loop controller or feedback controller.

In designing feedback controllers for dynamical systems a variety of modern, multivariable controllers are used.

The application to linear time-varying systems enables the design of linear feedback controllers for non-linear uncertain systems.

This simple model has been employed as a feedback controller to be applied to control design problems.

The input to a feedback controller is the same as what it is trying to control - the controlled variable is "fed back" into the controller.

The thermostat of a house is an example of a feedback controller.

For feedback controllers there are a few simple types.
