Abstract EN
This paper presents the robust stability analysis based on LMI for force feedback haptic interface systems with uncertain delay.
A full-order state observer is introduced to estimate states of the haptic device so as to directly obtain the feedback force, which expands the stability range of the system environment parameters when comparing with that of the system without an observer.
By using the delay partitioning idea and the augmented state vector, the Lyapunov-Krasovskii functional is constructed, and then the new stability criterion based on LMI is given in the paper.
With this new stability criterion, the observer gains can also be obtained directly.
At last, a concrete example is used to prove the effectiveness and less conservativeness of this new approach.
