Fast finite-time consensus of a class of high-order uncertain nonlinear systems
, 2010 This paper poses and solves a new problem of consensus control where the task is to make the fixed-topology multi-agent network, with each agent described by an uncertain nonlinear system in chained form, to reach consensus in a fast finite time.

Low-power wind energy conversion system with variable structure control for DC grids [PDF]
, 2013 This paper presents a discussion on the use of variable structure control, i.e., sliding mode control, for improving the dynamic control performance of a low-power wind energy conversion system (WECS) that is connected to a DC microgrid. The sliding mode

SICE Journal of Control, Measurement, and System Integration, 2017 This paper proposes a sliding mode control with an ellipsoidal sliding surface for vehicle distance control. The performance of two different sliding surfaces, namely ones that are ellipsoidal and linear, is evaluated under the same conditions.

Sliding mode control for a nonlinear phase-field system
, 2017 In the present contribution the sliding mode control (SMC) problem for a phase-field model of Caginalp type is considered. First we prove the well-posedness and some regularity results for the phase-field type state systems modified by the state-feedback

Global robust super-twisting algorithm with adaptive switching gains for a hybrid robot
International Journal of Advanced Robotic Systems, 2020 To improve the robustness performance of dynamic sliding mode control to the time-varying uncertainties without the upper bound information in a hybrid robot system, a global robust super-twisting algorithm with adaptive switching gains is proposed.
