Khayati, Karim, Auteur ; Bigras, Pascal, Auteur ; Dessaint, Louis-A., Auteur |The purpose of this paper is to develop an accurate closed-loop acting force technique for a pneumatic actuator, as an essential stage in the implementation of positioning control strategy. Since an analytical nonlinear structure, which linearly[...]

Khayati, Karim, Auteur ; Bigras, Pascal, Auteur ; Dessaint, Louis-A. |A historical review of constrained robot modeling and control strategies is first introduced. Next, a design of a motion/force controller for a constrained servo-robot, which is based on a commonly known modeling structure, is proposed. The cont[...]
