The flexible states of HFV are assumed to be unmeasurable with considering the measurement difficulties. Then a SMO is designed to estimated them. What is more, the measuring devices are assumed to be suffering from disturbance, then the SMO should not only guarantee the estimation error stable, but also reduce the influence of external disturbances. What’s worse, the input of HFV is suffering from input delay, which brings more difficulties to the controller design. By state transformation,input delay model of HFV is transformed into a delay free model,then a SMO based robust controller is proposed for HFV based on the stable inversion controller design strategy. Numeral simulation results are proposed for the validation of the presented method in the final.
