Parametric and Coordinate Control of Oscillating Systems: Physics-Based Oscillation Feedback Design

Blog Article

This paper presents and compares two practical implementation schemes based on parametric and coordinate control.The parametric feedback control idea employs a parametric resonance Chests phenomenon.An approximate frequency domain stationarization approach yields the setting for a very simple controller scheme.The application and numerical analysis of the results are given for the pendulum control example, which length varies in a parametric control case.

The coordinate and parametric control demonstrate similar damping properties.The study also provides an inventive Clothing - Junior Bottoms - Shorts idea for passive parametric control combined with coordinate control that shows better damping.
