In recent years, DC microgrid systems feeding constant power loads (CPLs) have been given a particular focus due to their effect on the overall system stability caused by electrical characteristics behaving as negative incremental impedance. To address this issue, paper investigates stabilization of bus voltage in (MG) CPL. The output main is stabilized using robust nonsingular terminal sliding...

In this paper, sensor fault diagnosis and tolerant control strategy are investigated for quadcopters under faults disturbances. We propose the estimation system fault-tolerant (FTC) method. The provides time-varying an unknown bound of Moreover, eliminates disturbance that is estimated through associated observer. Overall, proposed FTC guarantees finite-time tracking convergence using nonsingul...

This paper addresses the fixed-time stability analysis of a mobile unicycle-like system (UTMS) with chained shape dynamics (CFD) and subjected to unknown matched uncertainties. To achieve stabilization nonholonomic (NS) in CFD, an adaptive nonsingular fast terminal sliding mode control scheme (ANFTSMC) is proposed. determine upper bounds disturbances, only velocity position measurements are req...

In this study, an adaptive nonsingular finite time control technique based on a barrier function terminal sliding mode controller is proposed for the robust stability of nth-order nonlinear dynamic systems with external disturbances. The makes convergence tracking errors to region near zero in time. Moreover, suggested method does not need information upper bounds perturbations which are common...

This paper presents a nonsingular terminal sliding mode and active disturbance rejection decoupling control (NTSM-ADRDC) scheme for the three-dimensional (3D) trajectory tracking of autonomous underwater vehicles (AUV). Firstly, AUV model is decoupled into five independent single input–single output (SISO) channels using ADRDC technology. Secondly, NTSM-ADRDC controller designed. The linear ext...

Abstract System uncertainties and external disturbances are the major causes of trajectory tracking performance degradation in nonholonomic wheeled mobile robots (NWMRs). In this article, an adaptive fast nonsingular terminal sliding mode dynamic control (AFNTSMDC) method is proposed to provide enhanced robust finite-time for NWMR. The AFNTSMDC a systematic design based upon both kinematic mode...
