Simulation study of active vibration control of planetary gear: Theoretical and numerical analysis using pole placement

This paper presents analytical and numerical studies on the active assignment of poles to a planetary gear system for vibration control in order avoid resonance. involves feeding back displacement velocity add stiffness damping, respectively. A rotating frame reference has been adopted describe dynamics over broad range rotational speed. As an illustration, closed loop were assigned translational directions sun first thereafter carrier. can be achieved by placing actuators outer race their bearings mounted onto shafts. The controller was designed such that considering In this way, it is possible apply robust pole-placement insensitive Numerical examples, where sensors collocated, are presented demonstrate feasibility method when applied physical system. results shows force power required system, rotating, determined using transformed practical implementation. addition, same conjugate carrier optimal place forces discovered. depends upon shift from one location another. show more will gear, higher bearing required. Therefore, assign case due lower poles.
