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 ... -
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 ... -
A Fractional-Order Control Approach to Ramp Tracking with Memory-Efficient Implementation
Weise, Christoph; Tavares, Rafael Pinto; Wulf, Kai; Ruderman, Michael; Reger, Johann (Chapter, 2020)We investigate the fractional-order (FO) control of arbitrary order LTI systems. We show that, for ramp tracking or input disturbance rejection, it is advantageous to include an FO integrator to the open-loop if we have ... -
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 ... -
Parameter Identification of Fractional-Order LTI Systems using Modulating Functions with Memory Reduction
Weise, Christoph; Pfeffer, Philipp; Reger, Johann; Ruderman, Michael (Chapter, 2021)The parameter estimation problem of a linear time-invariant fractional-order system is investigated by means of the modulating function method. Based on the assumption of known model structure and derivative orders, the ...
