An Observer for Time Lag Systems

  title={An Observer for Time Lag Systems},
  author={Allan E. Pearson and Yawvi A. Fiagbedzi},
  journal={1987 American Control Conference},
An observer is presented for time lag systems described by state variable differential delay equations which dualizes a previously developed reducing transformation technique for state feedback stabilization. A system with delay in the state variables is shown to possess two characteristic matrix equations: a "left" matrix equation which arises in the feedback stabilization problem, and a "right" characteristic matrix equation which is shown to be central to the dualized observer problem.
