Abstract
This paper presents a smooth sliding mode control plus backstepping method for the motion/force control of a constrained robotic manipulator with flexible joints. The control scheme is presented based on that overall system parameters are with uncertainties whereas only the constrained force, positions and velocities of links and rotors are measurable. The smooth sliding controller can achieve zero motion and force tracking errors. The simulation results for a planar robot illustrate the expected satisfactory performance.
