Pseudo?active actuators: A concept analysis

The superior performance of active vibration control systems largely depends on the four-quadrant controllable execution capability in available force-velocity diagram actuators. Although semi-active have advantages low energy consumption, simple structure, and high reliability, system is not comparable to systems, due partial only first third quadrants. On basis comprehensive actuators, reform design philosophy actuators realize pseudo-active that both mechanical properties consumption is, new with capability, will very likely cause a revolution related fields control. basic principle use achieve actuator way conceptual analysis proposed. proposed should consist two half-four-quadrant one for quadrants other second fourth This study employs damping compensation mechanism.
