Wave Haptics: Building Stiff Controllers from the Natural Motor Dynamics
— Haptics, like the fields of robotics and motion control, relies on high stiffness position control of electric motors. Traditionally DC motors are driven by current amplifier...

Robust entrainment to natural oscillations of asymmetric systems arising from animal locomotion
We consider a class of linear flexible mechanical systems arising from the dynamics of animal locomotion. A distinctive property of such systems is that the stiffness matrix is asy...

Robust semiglobal stabilization of the second order system by relay feedback with an uncertain variable time delay
We present sufficient conditions for robust relay-delayed semiglobal stabilization of second order systems, which relate the upper bound to an uncertain time delay and the paramete...

Lyapunov-based switching control of nonlinear systems using high-gain observers
Abstract— We consider dynamic output feedback practical stabilization of uniformly observable nonlinear systems, based on high-gain observers with saturation. We assume that unce...

Stochastic control over finite capacity channels: Causality, feedback and uncertainty
Abstract-- Optimal communication/control analysis and design of dynamical controlled systems, when there are finite capacity communication constraints often involve information and...
