WebSep 19, 2024 · We will give an example that using additional harmonic excitation limitation of vibration amplitude is possible. Instead of constant speed S (dimensionless s = S (\textit {KM})^ {0.5}/F_ {0} ), we assume that s has an additional harmonic excitation \Delta {s}, WebFinally, a numerical example of linearized control through compensation loop is provided, demonstrating the interest in the proposed approach for providing a computationally-efficient, simple yet efficient way for finely predicting the actuator response and thus designing appropriate controllers. ...

Response to non-harmonic excitations - University of Florida
WebHarmonic excitation velocity is harmonic displacement multiplied by angular frequency ω, which is 2π multiplied by frequency f, and phase shifted by 90 degrees, which in complex notation means multiplied by i. Acceleration is velocity multiplied by ω and phase shifted another 90 degrees, so multiplied by another i. d = displacement v = velocity rock and roll hall of fame performers
