The future More Electric Aircraft (MEA) technology focus on increasing the use of electrical equipment to a larger extent, e.g. replacing conventional hydraulic and pneumatic actuators with electromechanical or electro hydrostatic actuators to reduce weight, cost and maintenance. Advances in enabling technologies of electric power generation, distribution, and utility equipment have made the us...

Linear electro-mechanical actuators are finding increased use in the field of thrust vectoring of launch vehicles. Earlier, linear electro-hydraulic actuators were used especially in the lower stages of the launch vehicles where there is a requirement for large actuation forces. However, electro-mechanical actuators are being scrutinized for this purpose in an effort to provide lighter, cleaner...

Series Elastic Actuators provide many benefits in force control of robots in unconstrained environments. These benefits include high force fidelity, extremely low impedance, low friction, and good force control bandwidth. Series Elastic Actuators employ a novel mechanical design architecture which goes against the common machine design principal of “stiffer is better”. A compliant element is pl...

This paper presents a robust machine learning framework for modeling and control of hydraulic actuators. We identify several important challenges concerning accurate models the dynamics real machines, including noise uncertainty in state measurements, nonlinear effects, input delays, data-efficiency. In particular, we propose dual-Gaussian process (GP) model architecture to learn surrogate actu...
