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.
