Analog cross coupled controller for oscillations: modeling and design via dominant system theory
Weiming Che, Thomas Chaffey, Fulvio Forni
We propose a new analog feedback controller based on the classical cross coupled electronic oscillator. The goal is to drive a linear passive plant into oscillations. We model the…

Shaping oscillations via mixed feedback
W. Che, F. Forni
We study the problem of controlling oscillations in closed loop by combining positive and negative feedback in a mixed configuration. We develop a complete design procedure to set…

A tunable mixed feedback oscillator
Weiming Che, Fulvio Forni
The interplay of positive and negative feedback loops on different time scales appears to be a fundamental mechanisms for robust and tunable oscillations in both biological systems…
