Rechen- und laufzeitoptimierte Implementierung von adaptiven Steuerungen durch digitale Signalverarbeitung mit Multi-rate Algorithmen

Kurzfassung

This work is an attempt to find suitable multi-rate (MR) algorithms for an adaptive control by means of an active structural acoustic control (ASAC). For a practical application these MR algorithms are implemented as single-input-single-output (SISO) systems. The systems are compared to traditional adaptive controls taking into account run time and control success. Furthermore, alternative structures of MR systems are presented and compared with respect to delay, control performance and computational efficiency. Effects produced by MR components are discussed in detail and questions regarding causality and filter selection are investigated thoroughly.
