Observer based state feedback controller design of a DC servo motor using identified motor model: an experimental study

Full state feedback is a commonly used technique in control systems. However, full state feedback control implementation requires knowledge of the entire state vector of the system which is not always possible. Thus, observers are used to estimate the immeasurable states which are then used for state feedback control. This work presents an experimental procedure to control the angular position of a DC servo motor using state feedback control law. The process involves system identification, followed by observer and controller design using separation principle.
