About

Helmut Kogler is a leading researcher in the field of fluid power and hydraulic actuation, with a particular focus on energy efficiency and advanced control strategies for robotics. His work bridges the gap between traditional hydraulic systems and modern switching technologies, drawing inspiration from power electronics to revolutionize hydraulic actuation. Kogler’s major contributions include pioneering the application of switched-mode control to hydraulics, as demonstrated in his highly cited 2010 paper on “Power hydraulics - switched mode control of hydraulic actuation” (26 citations), which explores how faster static switches can enhance hydraulic system performance. He has also made significant strides in autonomous legged robotics, notably through his 2009 study on “Energy Efficient Fluid Power in Autonomous Legged Robotics” (25 citations), where he developed a hydraulic drive for a bioinspired quadruped robot leg, comparing classical valve-controlled systems with energy-efficient alternatives. Additionally, Kogler’s 2013 paper on “The use of a hydraulic DC-DC converter in the actuation of a robotic leg” (12 citations) introduced a Hydraulic Buck Converter to improve efficiency in the HyQ quadruped robot’s actuation. His work is instrumental in advancing energy-efficient, high-power-density hydraulic systems for robotics and industrial applications.
