Abstract Several active damping methods corresponding to various reference systems are discussed. The theoretical analyses show that a quasi-fixed reference system can be used to improve the high-frequency performance of a multi-stage active damping system because its high-frequency performance is equivalent to that of a low-pass electronic filter with a very low cut-off frequency.
