This paper proposes a procedure for the real-time detection of low-frequency components within the spectrum of a signal related to a monitored quantity. The problem is common within different domains, such as medical diagnostics, mechanics, geology, and the monitoring of human activities. This procedure has also been specifically designed to allow the detection of more than one component, with a good...
In the paper a procedure for real-time detection of low frequencies is proposed, and it is customized for detecting very low frequency and slightly higher frequency components. The case study is focused on the observation of a Magnetorheological suspension system installed on a commercial motorbike: the resonance frequencies due to the sprung mass and due to the unsprung masses are monitored. Tests...
Active and semi-active suspension systems allow to obtain the best compromise between ride comfort and road holding. These systems analyze signals describing the vehicle status and react to unwanted vibrations on the basis of the control strategy. The analysis of the signals in the frequency domain can improve the control action, since incoming vibration can be properly detected. In this paper a method...
