This work presents new results on the configuration and methods for the implementation of actively damped engine suspension systems that include a chassis subframe. In particular, a thorough analysis concerning the determination of effective and energy-saving arrangements of the electro-mechanical actuators in the setup is performed. Furthermore, a novel analysis of the convergence behavior of the well known filtered-X LMS algorithm, especially for the relevant excitation with multiple harmonic sinusoids, is presented. Finally, the applicability and performance of four different types of algorithms for the software realization of the active damping system is investigated and discussed. Necessary modifications of the algorithms are explained and their behavior is compared in experiments for stationary and non stationary excitation. The most promising of the examined control structures are extended to centralized multichannel systems.
