Permanent magnet synchronous motors (PMSMs) are known as highly efficient motors and
are slowly replacing induction motors in diverse industries. PMSM systems are nonlinear …

The implementation of sliding mode control is often irritated by high frequency oscillations
known as “chattering” in system outputs issued by dynamics from actuators and sensors …

Control in the presence of uncertainty is one of the main topics of modern control theory. In
the formulation of any control problem there is always a discrepancy between the actual …

We propose a backstepping global fast terminal sliding mode control for trajectory tracking
control of industrial robotic manipulators in this article. An integral of the global fast terminal …

This article introduces predefined-time stable dynamical systems which are a class of fixed-
time stable dynamical systems with settling time as an explicit parameter that can be defined …

Sliding mode control (SMC) is attractive for nonlinear systems due to its invariance for both
parametric and nonparametric uncertainties. However, the invariance of SMC is not …

This paper develops a sliding-mode control (SMC) approach for systems with mismatched
uncertainties via a nonlinear disturbance observer (DOB). By designing a novel sliding …

Urban search and rescue missions raise special requirements on robotic systems. Small
aerial systems provide essential support to human task forces in situation assessment and …

An adaptive sliding mode fault‐tolerant control strategy is proposed for a quadrotor
unmanned aerial vehicle in this article to accommodate actuator faults and model …

This paper presents an adaptive robust controller for robot manipulators using adaptive
integral sliding mode control and time-delay estimation (TDE). The proposed controller …
