Abstract :
This paper proposes a continuous-time model estimation method by using the unscented Kalman filter (UKF) from the sampled I/O data, in which the initial state as well as the plant parameter are estimated. The initial state is estimated based on a backward system of the plant. The effectiveness is demonstrated by using the rotary inverted pendulum (RIP) to estimate the initial state and the parameter of a continuous-time nonlinear system.
