Control damping for elastic vibrations of a distributed system with the sensor — actuator overcharge

Abstract

This project develops the modal control system for vibration damping of an elastic object with distributed parameters. Non-controllable upper modes excitement sets a limit on control efficiency of individual lowest elastic mode damping. The study tests the control operability in relation to the changing sensor — actuator number while the feedback loops remains the same. Simulation results show spillover effect degradation in case the sensor — actuator overcharge. Control algorithm includes of identification procedure instead of designing with the object model assistance. The present procedure puts the modal matrices to separate the inherent object modes from the sensor signals and to suppress the modes using the actuators.
