Abstract

An observer-based controller is a dynamic feedback controller with a two-stage structure. First, the controller generates an estimate of the state variable of the system to be controlled, using the measured output and known input of the system. This estimate is generated by a state observer for the system. Next, the state estimate is treated as if it were equal to the exact state of the system, and it is used by a static state feedback controller. Dynamic feedback controllers with this two-stage structure appear in various control synthesis problems for linear systems. In this entry, we explain observer-based control in the context of internal stabilization by dynamic measurement feedback.
