Abstract [en]

The performance of a modified parallel control scheme is examined under surfacekinematic uncertainties using nonlinear stability analysis. The controlled system is a roboticfinger with a soft hemispherical fingertip of significant radius in contact with an unknownsurface. Analysis of the control system performance shows that force converges to the desiredvalue, whereas position errors stay close to zero and in some cases can even vanish despite uncertainties. Simulation results support the theoretical findings and illustrate the performance of theproposed controller.
