Robust asymptotic observer of motion states with nonlinear friction
Michael Ruderman
This paper revisits the previously proposed linear asymptotic observer of the motion state variables with nonlinear friction and provides a robust design suitable for both, transie…
Time-delay based output feedback control of fourth-order oscillatory systems
Michael Ruderman
We consider a robust stabilization of the fourth-order oscillatory systems with non-collocated output sensing. Worth recalling is that the fourth-order systems are relatively commo…
Energy dissipation and hysteresis cycles in pre-sliding transients of kinetic friction
Michael Ruderman
The problem of transient hysteresis cycles induced by the pre-sliding kinetic friction is relevant for analyzing the system dynamics e.g. of micro- and nano-positioning instruments…
Sensitivity analysis and experimental evaluation of PID-like continuous sliding mode control
Michael Ruderman, Johann Reger, Benjamin Calmbach +1
Continuous higher order sliding mode (CHOSM) controllers represent an efficient tool for disturbance rejection. For the systems with relative degree r, CHOSM approaches provide the…
Motion control with optimal nonlinear damping: from theory to experiment
Michael Ruderman
Optimal nonlinear damping control was recently introduced for the second-order SISO systems, showing some advantages over a classical PD feedback controller. This paper summarizes…
Comparison of Fractional-Order and Integer-Order H-infinty Control of a Non-Collocated Two-Mass Oscillator
Benjamin Voß, Michael Ruderman, Christoph Weise +1
We consider the robust control of a two-mass oscillator with a dominant input delay. Our aim is to compare a fractional-order tuning approach including the partial compensation of…
