- W1990094345 abstract "The modified positive position feedback controller, an active vibration control method that uses collocated piezoelectric actuator actuators and sensors, is developed using an adaptive controller. The adaptive mechanism consists of two main parts: 1) Frequency adaptation mechanism, and 2) Adaptive controller. Frequency adaptation only tracks the frequency of vibrations using Fast Fourier Transforms. The obtained frequency is then fed to MPPF compensators and the adaptive controller. This provides a unique feature for MPPF, by extending its domain of capabilities from controlling tonal vibrations to broad band disturbances. The adaptive controller mechanism consists of a reference model that is of the same order as the MPPF system and its compensators. The adaptive law provides the additional control force that is needed for controlling frequency changes caused by broad band vibrations. The experimental results show that the frequency tracking method that is derived has worked quite well. The results also indicate that the MPPF can provide significant vibration reduction on a cantilever beam that is used throughout the experiments." @default.
