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

Robust Integral Sliding-Mode Control of an Aerospace Launch Vehicle

An analysis of on-line autonomous robust tracking controller based on variable structure control is presented for an aerospace launch vehicle. Decentralized sliding-mode controller is designed to achieve the decoupled asymptotic tracking of guidance commands upon plant uncertainties and external disturbances. Development and application of the controller for an aerospace launch vehicle during a...

Robust Sliding Mode Control for a Class of Uncertain Switched Neutral Systems

In this paper, the method of robust sliding mode control for a class of switched neutral control systems with mismatched fractional form parametric uncertainties is investigated. A delay-dependent sufficient condition for the existence of linear sliding surfaces is given in term of linear matrix inequality(LMI), and sliding mode controllers based on reaching law are developed, which are to ensu...

Robust nonlinear generalised predictive control for a class of uncertain nonlinear systems via an integral sliding mode approach

Second Order Sliding Mode Observer-Based Control for Uncertain Nonlinear MEMS Optical Switch

This paper studies theuncertain nonlinear dynamics of a MEMS optical switch addressing electrical, mechanical and optical subsystems. Recently, MEMS optical switch has had significant merits in reliability, control voltage requirements and power consumption. However, an inherent weakness in designing control for such systems is unavailability of switch position information at all times due to t...

Robust observer with sliding mode estimation for nonlinear uncertain systems

To handle the state estimation of a nonlinear system perturbed by a scalar disturbance distributed by a known nonlinear vector, we incorporate a sliding mode term into a nonlinear observer to realise a robust nonlinear observer. By linking the observability of the unknown input to the output measurement, the so-called matching condition is avoided. The measurable output estimation error is the ...
