In this paper, a new alternative for profiles tracking control considering additive uncertainties is proposed. Based on previously presented work about nonlinear and multivariable controller design fed-batch bioethanol production, parametric uncertainty process disturbance are taken into account to find more reliable strategy successful industrial implementation. To decrease the effect, an appr...

A control system combining input shaping and feedback is applied to a double-pendulum bridge crane subjected to external disturbances. The external disturbances represent naturally occurring forces, such as gusting winds. The proposed control method achieves fast point-to-point response similar to open-loop input-shaping control. It also minimizes transient deflections and disturbance-induced r...

New stability results are presented for Kelly’s algorithm for network traffic control. These are applicable to a broad class of algorithms including most of those previously discussed in the literature. Three types of results are derived; an asymptotic stability result for networks with external disturbances but without time delays, an asymptotic stability result for a class of algorithms with ...

Abstract A sliding mode control (SMC) with improved exponent reaching law based on disturbance observer (DOB) is proposed for the robot control, to solve the problem of robot system which is vulnerability to external interferences and has some uncertainties. The disturbance observer (DOB) would detect and compensate external disturbances and uncertainties in the robot system, so that the moveme...

Environmental conditions, including anthropogenic disturbance, can significantly alter host and parasite communities. Yet, our current knowledge is based mainly on endoparasites, while ectoparasites remain little studied. We studied the indirect effects of anthropogenic disturbance (human population density) and climate (temperature, precipitation and elevation) on abundance of highly host-spec...

We show that existence of a non-coercive Lyapunov function is sufficient for uniform global asymptotic stability (UGAS) of infinite-dimensional systems with external disturbances provided an additional mild assumption is fulfilled. For UGAS infinite-dimensional systems with external disturbances we derive a novel ’integral’ construction of non-coercive Lipschitz continuous Lyapunov functions. F...
