Online Reconfiguration of a Variable-Stiffness Actuator [PDF]
IEEE/ASME Transactions on Mechatronics, 2018 This paper presents an algorithm to adjust the configuration of a variable-stiffness actuator to reduce its electrical energy requirements during the execution of repetitive tasks. The algorithm is based on the gradient descent optimization method with a modification of the adaptation step size, a forgetting term, and a projection rule to cope with the

Variable Stiffness Actuators: A Port-Based Power-Flow Analysis
IEEE Transactions on Robotics, 2012 Variable stiffness actuators realize a novel class of actuators, which are capable of changing the apparent output stiffness independently of the output position. This is mechanically achieved by the internal introduction of a number of elastic elements and a number of actuated degrees of freedom (DOFs), which determine how the elastic elements are ...

Temperature sensitive controller performance of MR dampers [PDF]
, 2009 Magnetorheological (MR) dampers can experience large temperature changes as a result of heating caused by energy dissipation, but control systems are often designed without consideration of this fact.

Analysis of Variable-Stiffness Characteristics of Variable-Stiffness Elastic Actuator
, 2023 In order to improve the stiffness of the flexible robot,this paper proposes a variable-stiffness elastic actuator to improve the rigidity of flexible robots. The actuator integrates the working principles of a pneumatic drive, wedge structure, and particle blockage. the tensile stiffness of the actuator is nonlinearly negatively correlated with the air
