Comparison of Formulas Obtained for Analytical and LQ Idea Approaches to Determine the Optimal Actuator Location in Active Multimodal Beam Vibration Reduction

Elżbieta ŻOŁOPA

Rzeszów University of Technology

In this paper an active general beam vibration reduction via one actuator is considered. The optimal actuator distribution is analyzed with two methods: an exact mathematical principles and the LQ problem idea. It turned out, that the same mathematical expressions are derived. So these methods are equivalent.
Keywords: beam, actuator, active vibration reduction, LQ problem, system control, control of vibration.
