Abstract
Methods and devices for enhancing shudder stability in servo systems comprising hydro-mechanically driven actuators are disclosed. Series damping devices forming compliant couplings having series damping characteristics are disclosed. The series damping devices are utilized for mounting the hydro-mechanically driven actuators or coupling them to load elements which they position. The improvement consisting of providing series damping associated with the hydro-mechanically driven actuators for absorbing sufficient energy to provide adequate gain and phase margins for the open-loop feedback characteristics of systems utilizing the hydro-mechanically driven actuators in order to substantially prevent high frequency shudder from occurring during operation of the systems.
