Novel Direct and Accurate Identification of Kalman Filter for General Systems Described by a Box-Jenkins Model

Abstract: A novel robust Kalman filter (KF)-based controller is proposed for a multivariable system to accurately track a specified trajectory under unknown stochastic disturbance and measurement noise. The output is a sum of uncorrelated signal, disturbance and measurement noise. The system model is observable but not controllable while the signal one is controllable and observable. An emulator-based two-stage identification is employed to obtain a robust model needed to design the robust controller. The system and KF … Show more
