Abstract EN
This paper presents a new approach for constructing a mathematical model of the floating raft system directly from input-output measurements in the presence of noise.
In contrast to the original OKID/ERA algorithm, which works through the observer Markov parameters, the new approach used observer output residuals to convert the initial stochastic identification to a virtually deterministic identification problem.
The extension of deterministic algorithm to stochastic problems by proposed stochastic-to-deterministic conversion can be done with ease.
A MIMO (multiple-input multiple-output) system state-space model and an associated Kalman filter gain can be identified.
H∞ controller with high robustness to model error is designed to solve multifrequency varying vibration for floating raft system.
Both simulated and experimental results confirm the validity and the benefits of the approach.
