Module overview.
The main design approach for systems described in
state-space form is the use of state feedback. One selects pole
locations to achieve a satisfactory dynamic response and develops
the control law for the closed-loop system that corresponds to
satisfactory dynamic response. One has to design an estimator for
the states, because these are generally not measurable. This
estimator is an observer that delivers the information about the
states so that they can be used for control. The combined
observer-controller problem is discussed. Several pole-placement
designs for controllers with proportional and integral state
feedback and observers based on controller canonical form are
given. A comprehensive example shows the overall design
procedure.
