Controllers for attenuation of lateral rotor vibration part II: Controller optimization and comparison

Abstract

In part I of this two-part article, three feedback controllers from different fields of research and a feedforward controller have been discussed. In this part II, feedback controllers are optimized to identify the optimum performance which is not necessary for the feedforward controller since it is self-adapting. The four controllers are compared against each other on the basis of their optimal control performance. Results are validated experimentally.
