  4. Abstract:
  5. An LQ-based tracker is designed in this paper, using output feedback. For performing the design, at first, a structured controller is introduced for a set of equations. The controller is obtained by mini-mizing a cost function which has some penalties on both the system's inputs and states. After that, an estimator is introduced and combined with the controller to close the loop. Running the nonlinear simulation at the end verifies the superiority of Extended Kalman Estimator (EKF)to the Linear Kalman Estimator (LKF). © 2005 IEEE
