Excitation of the inverted pendulum device installed under observatory grade conditions. (A) A complex wave with broadband spectrum content (fast over slow) excites the mass of the EPS. (B) Oscillation of the mass of the EPS in the high-frequency component due to the lack of the fast feedback node. In this case, the long period excitation is effectively compensated. Shaded circle in (C) indicates the blocked fast feedback node. (D) Oscillation of the mass of the EPS in response to the long period component of the complex wave. Shaded circle in (E) indicates the blocked integrator of the feedback loop.
