In this paper, adaptive filtering algorithm for control of the vibration force applied on the specimen in testing control systems is presented. Application for adaptive filtering especially in Time Domain is associated with a high computational complexity. This complexity is mitigated by using frequency-domain adaptive filtering scheme. In this paper adaptive filtering algorithm in association with Fast Fourier Transformation (FFT) was proposed. The algorithm was implemented using Digital Signal Processor (DSP). The proposed algorithm show significant reduction in computational complexity as shown in results and discussion.
Key words: Hybrid frequency-time, adaptive filtering algorithm, electrodynamics shaker
