Ruderman, Michael; Iwasaki, Makoto; Chen, Wen-Hua (Peer reviewed; Journal article, 2020)The paper states that continued progress in integrated mechatronic design and novel actuator technologies has created new challenges for motion control technologies. -
On break-away forces in actuated motion systems with nonlinear friction
Ruderman, Michael (Journal article; Peer reviewed, 2017)The phenomenon of so-called break-away forces, as maximal actuation forces at which a sticking system begins to slide and thus passes over to a steady (macro) motion, is well known from the engineering practice but still ... -

On stability of linear dynamic systems with hysteresis feedback
Ruderman, Michael (Journal article; Peer reviewed, 2020)The stability of linear dynamic systems with hysteresis in feedback is considered. While the absolute stability for memoryless nonlinearities (known as Lure’s problem) can be proved by the well-known circle criterion, the ... -
On stability of linear dynamic systems with hysteresis feedback
Ruderman, Michael (Journal article; Peer reviewed, 2020)Abstract. The stability of linear dynamic systems with hysteresis in feedback is considered. While the absolute stability for memoryless nonlinearities (known as Lure’s problem) can be proved by the well-known circle ... -
On Stability of Virtual Torsion Sensor for Control of Flexible Robotic Joints with Hysteresis
Ruderman, Michael (Journal article; Peer reviewed, 2019)Aim of the virtual torsion sensor (VTS) is in observing the nonlinear deflection in the flexible joints of robotic manipulators and, by its use, improving positioning control of the joint load. This model-based approach ... -
On stiffness and damping of vibro-impact dynamics of backlash
Ruderman, Michael (Chapter, 2021)We consider the instantaneous stiffness and damping of the vibro-impact in a backlash pair. Opposed to the existing and mostly used models of the backlash, we address the problem of contact and separation, and the associated ... -

Optimal nonlinear damping control of second-order systems
Ruderman, Michael (Journal article; Peer reviewed, 2021)Novel nonlinear damping control is proposed for second-order systems. The proportional output feedback is combined with the damping term which is quadratic to the output derivative and inverse to the set-point distance. ... -
