This study describes the design, instrumentation and control of an exoskeleton for lower limb
children rehabilitation with nine degrees of freedom. Three degrees of freedom in each leg …

This paper deals with the estimation of unknown signals in bioreactors using sliding
observers. Particular attention is drawn to estimate the specific growth rate of …

This brief proposes an adaptive version of a second-order sliding mode (SOSM) controller
with a gain for which switching variations are forced under some adequate conditions. The …

This paper proposes two high-order sliding mode algorithms to achieve highperformance
control of induction motor drive. In the first approach, the super-twisting algorithm (STA) is …

In this work, we aim to apply an adaptive Higher order sliding mode controller for trajectory
tracking mode of Multi-rotor Unmanned Aerial Vehicles (UAVs) such as a Quadrotor system …

This paper proposes a novel adaptive-gain second order sliding mode controller. The
proposed controller is based on discontinous-impulsive action and only uses information of …

In this paper, the output tracking problem for a class of systems with unstable zero dynamics
is addressed. The state is assumed not measurable. The output of the dynamical system to …

The suspension system is faced with nonlinearities from the spring, damper, and external
excitations from the road surface. The objective of any control action provided to the …

An adaptive output feedback is presented. The adaptive gain is used to relax the restriction
of knowing the perturbation bound. it is proved that with the adaptive gain both, the controller …
