Analysis of relay-based feedback compensation of Coulomb friction
Ruderman, Michael; Fridman, Leonid M. (Peer reviewed; Journal article, 2022)Standard problem of one-degree-of-freedom mechanical systems with Coulomb friction is revised for a relay-based feedback stabilization. It is recalled that a system with Coulomb friction is asymptotically stabilizable via ... -
Backlash Identification in Two-Mass Systems by Delayed Relay Feedback

Comparison of Fractional-Order and Integer-Order H-infinity Control of a Non-Collocated Two-Mass Oscillator
Voss, Benjamin; Ruderman, Michael; Weise, Christoph; Reger, Johann (Journal article, 2022)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 non-minimum phase zeros with a classical ... -
Convergent dynamics of optimal nonlinear damping control
Ruderman, Michael (Peer reviewed; Journal article, 2021)Following the Demidovich’s concept and definition of convergent systems, we analyze the optimal nonlinear damping control which was recently proposed for the second-order systems. Targeting the problem of servo-regulation, ... -

Dissipation in suspension system augmented by piezoelectric stack: port-Hamiltonian approach
Tavares, Rafael Pinto; Ruderman, Michael (Chapter, 2020)Analysis of damping in semi-active and active suspension systems is prerequisite for an advanced control and, eventually, energy harvesting functions. This paper addresses the damping in suspension system augmented by the ... -
Dynamics of inertial pair coupled via frictional interface
Ruderman, Michael; Zagvozdkin, Andrei; Rachinskii, Dmitrii (Peer reviewed; Journal article, 2022)Understanding the dynamics of two inertial bodies coupled via a friction interface is essential for a wide range of systems and motion control applications. Coupling terms within the dynamics of an inertial pair connected ... -
Energy dissipation and hysteresis cycles in pre-sliding transients of kinetic friction
Ruderman, Michael (Peer reviewed; Journal article, 2023)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 and devices and their controlled ... -

Estimating Sway Angle of Pendulum System Using Hybrid State Observer Incorporating Continuous and Discrete Sensing Signals
Ano, Shuta; Seki, Kenta; Ruderman, Michael; Iwasaki, Makoto (Peer reviewed; Journal article, 2020)This paper presents the design of a hybrid state observer that estimates the sway angle in trolley systems with a pendulum, such as overhead cranes. In the system, sway angle signals detected by angular sensors are generally ... -
Experimental Evaluation of Homogeneous Differentiators Applied to Hydraulic Stroke with Measurement Noise and Acceleration Disturbance
Calmbach, Benjamin; Ruderman, Michael; Reger, Johann (Chapter, 2024)The design and experimental evaluation of continuous homogeneous differentiators are considered. The differentiator gains follow the high-gain setup with variable gain-scaling parameter L. This parameter results from a ... -

Fractional-Order Partial Cancellation of Integer-Order Poles and Zeros
Voss, Benjamin; Weise, Christoph; Ruderman, Michael; Reger, Johann (Chapter, 2022)The key idea of this contribution is the partial compensation of non-minimum phase zeros or unstable poles. Therefore the integer-order zero/pole is split into a product of fractional-order pseudo zeros/poles. The amplitude ... -
