Passivity Analysis of Discrete-time Counterparts of the Bilateral Controlled Teleoperation Systems
A. A. Ghavifekr, M. A. Badamchizadeh, A. R. Ghiasi +1
This paper presents an analysis of the passivity condition for discrete-time bilateral teleoperation systems. Considering discrete-time controllers for a master-slave teleoperation…
An Analysis of Sampling Effect on the Absolute Stability of Discrete-time Bilateral Teleoperation Systems
Amir Aminzadeh Ghavifekr, Seyedshahab Chehraghi, Giacomo De Rossi
Absolute stability of discrete-time teleoperation systems can be jeopardized by choosing inappropriate sampling time architecture. A modified structure is presented for the bilater…
Designing adaptive robust extended Kalman filter based on Lyapunov-based controller for robotics manipulators
AR Ghiasi, AA Ghavifekr, Y Shabbouei Hagh +1
In this paper, a position and velocity estimation method for robotic manipulators which are affected by constant bounded disturbances is considered. The tracking control problem is…
Discrete-time control of bilateral teleoperation systems: a review
Amir Aminzadeh Ghavifekr, Amir Rikhtehgar Ghiasi, Mohammad Ali Badamchizadeh
The possibility of operating in remote environments using teleoperation systems has been considered widely in the control literature. This paper presents a review on the discrete-t…
Stability analysis of the linear discrete teleoperation systems with stochastic sampling and data dropout
Amir A Ghavifekr, Amir R Ghiasi, Mohammad A Badamchizadeh +2
This paper addresses the stability conditions of the sampled-data teleoperation systems consisting continuous time master, slave, operator, and environment with discrete time contr…
Evaluation of Three Nonlinear Control Methods to Reject the Constant Bounded Disturbance for Robotic Manipulators
Amir. A. Ghavifekr, Saeed Pezeshki, Arash Arjmandi
In this paper, we consider the tracking control problem for robot manipulators which are affected by constant bounded disturbances. Three control schemes are applied for the proble…
