Observer-Based Robust Passive Control for a Class of Uncertain Neutral Systems: An Integral Sliding Mode Approach

Abstract EN

The problem of integral sliding mode control (ISMC) with passivity is investigated for a class of uncertain neutral systems with time-varying delay (NTSTD) and external disturbance.

The system states are unavailable.

An ISMC strategy is proposed based on the state estimate.

By employing a novel sliding functional, a new sufficient criterion of robust asymptotic stability and passivity for both the error system and the sliding mode (SM) dynamic system is derived via linear matrix inequality (LMI) technique.

Then, a SM controller is synthesized to guarantee the reachability of the sliding surface predefined in the state estimate space.

Finally, a numerical example shows the feasibility and superiority of the obtained result.
