About

Bernd Orlik is a control systems researcher whose work focuses primarily on robust control of nonlinear mechanical systems, with particular emphasis on elastically coupled multi-mass systems found in robotics, machine tools, and industrial applications. His research addresses the challenging real-world phenomena these systems exhibit, including limit cycles, stick-slip effects, and damaging torsional loads caused by dynamic load changes. Orlik's most significant contributions lie in the development of robust H∞ control strategies for two-mass systems, combining advanced output-feedback control with nonlinear observers to achieve precise positioning despite nonlinearities introduced by mechanical components such as gears and shafts. His landmark 2003 papers on robust output-feedback H∞ control with nonlinear observers have collectively attracted over 115 citations, establishing him as a key reference in this specialized field. His earlier 2002 work on state-feedback H∞ control laid important groundwork for these developments. Beyond two-mass systems, Orlik extended his research to more complex multi-mass configurations, proposing control strategies that minimize mechanical stress during dynamic load changes — work with direct relevance to wind energy plants and robotics. His body of work represents a consistent and focused contribution to bridging robust control theory with practical industrial applications.
