This paper presents the design of a multi-master-single-slave nonlinear tele-robotic system working in the presence of time varying delays. The structure of the proposed tele-robotic system is derived from the extended state convergence architecture

State convergence is a novel scheme to control a teleoperation system in a bilateral mode. Starting from modeling an nth order teleoperation system on state space, the scheme offers a simple and elegant procedure, which requires 3n+1 design condition

Adaptive decayed brain emotional learning (ADBEL) network is recently proposed for the online time series forecasting problems. As opposed to other popular learning networks, such as multilayer perceptron, adaptive neuro-fuzzy inference system, and l

Although particle swarm optimization (PSO) in its standard form performs extremely well for less complicated convex optimization problems involving reduced search space, it fails in finding global optimal solutions for more complicated nonconvex opti

Based on the limbic system theory of mammalian emotional brain, supervised brain emotional learning-based pattern recognizer (BELPR) has been recently proposed for multi-input and multi-output classification problems. It offers features like: decreas

To bilaterally control an n th-order teleoperation system modeled on state space, state convergence methodology provides an elegant way to design control gains through a solution of 3 n + 1 equations. These design conditions are obtained by allowing

Most of the traditional PID tuning methods are heuristic in nature. The heuristic approach-based tuned PID controllers show only nominal performance. In addition, in the case of a digital redesign approach, mapping of the heuristically-designed conti

This paper presents the design of a state convergence (SC)-based bilateral controller for a nonlinear teleoperation system, which has been approximated by a Takagi-Sugeno (TS) fuzzy model. The selection of SC is made due to the advantages offered by

Although an analytical design approach-based digital controller—which is essentially a deadbeat controller—shows zero steady-state error and no intersampling oscillations, it takes a finite number of sampling periods to settle down to a steady-st
