A Generalized Forced Oscillation Method for tuning Proportional Resonant Controllers
This paper proposes a tuning methodology for proportional resonant (PR) controllers by using the design philosophy of the Ziegler-Nichols forced oscillation method. Unlike such related methods that are usual for PID design, and those that have been recently proposed for PR controllers, the method in this paper is not restricted to plants whose Nyquist diagram crosses the negative real axis. It involves a feedback experiment with a relay of adjustable phase, which allows the identification of the most appropriate point of the frequency response for each class of plants. The validation of the proposed method, which includes the identification experiment and specific tuning formulas that provide appropriate stability margins for each class of plants, is performed by means of numerical examples in a large variety of plants, showing its wide applicability.

A model-free tuning method for proportional-multi-resonant controllers
Resonant controllers are widely used in applications involving reference tracking and disturbance rejection of periodic signals. The controller design is typically performed by a trial-and-error approach or by means of t…
Graph-Facilitated Resonant Mode Counting in Stochastic Interaction Networks
Oscillations in a stochastic dynamical system, whose deterministic counterpart has a stable steady state, are a widely reported phenomenon. Traditional methods of finding parameter regimes for stochastically-driven reson…

Hybrid integrator-gain system based integral resonant controllers for negative imaginary systems
We introduce a hybrid control system called a hybrid integrator-gain system (HIGS) based integral resonant controller (IRC) to stabilize negative imaginary (NI) systems. A HIGS-based IRC has a similar structure to an IRC…
