A Probabilistic Approach Towards Robust Stability Optimization, with application to vibration control
Original language description
The main results of this paper concern the positioning and robust stability optimization of a mechanical system, to which a so-called delayed resonator is attached in order to absorb harmonic perturbations. Due to the inclusion of this active vibration suppression device, the overall closed-loop system is described by delay differential algebraic equations of retarded type. The stability optimization, thereby taking into account uncertainty on the mathematical model, is achieved by the design of static and dynamic controllers evaluated by minimizing an objective function, consisting of the mean of the spectral abscissa, the real part of the rightmost eigenvalue, with a variance penalty. The analysis and the dynamics of the system show the validity, efficacy and robustness of the novel approach, with respect to the results obtained by stability optimization without taking into account the uncertainty.
