Abstract :
The identification of a linear discrete-time control system´s open-loop gain is addressed. The classical Kalman filter theory for state estimation in linear control systems is extended, and the control system´s loop gain and states are jointly estimated. A rigorous analysis of the measurement situation on hand yields explicit formulae for the loop gain´s unbiased estimate and estimation error´s covariance
