Journal ArticleDOI
Nonlinear Disturbance Observer Design For Robotic Manipulators
TL;DR: In this paper, a general systematic approach is proposed to solve the disturbance observer design problem for robotic manipulators without restrictions on the number of degrees of freedom (DOF), the types of joints, or the manipulator configuration.
Journal ArticleDOI
Colonial competitive algorithm A novel approach for PID controller design in MIMO distillation column process
TL;DR: CCA, a novel socio‐politically inspired optimization strategy, is used to tune the parameters of a multivariable PID controller for a typical distillation column process.
Journal ArticleDOI
Prescribed performance distance-based formation control of Multi-Agent Systems
TL;DR: In this paper, the authors presented a novel control protocol for robust distance-based formation control with prescribed performance in which agents are subjected to unknown external disturbances, in which connectivity maintenance and collision avoidance among neighboring agents are also handled by the appropriate design of certain performance bounds that constrain the inter-agent distance errors.
Journal ArticleDOI
Teleoperation in the presence of varying time delays and sandwich linearity in actuators
TL;DR: A novel control scheme is proposed to guarantee global asymptotic stability of bilateral teleoperation systems that are subjected to time-varying time delays in their communication channel and sandwich linearity in their actuators, which is called nonlinear proportional plus damping (nP+D).
Journal ArticleDOI
Position and force tracking in nonlinear teleoperation systems under varying delays
TL;DR: Stability and tracking performance of the teleoperation system are proved using a proposed Lyapunov–Krasovskii functional to guarantee position and force tracking in nonlinear teleoperation systems subject to varying communication delays.
