H∞ loop shaping control for distributed PLL network
Résumé
In this paper, we describe a robust control law for distributed PLL network using H∞ optimization problem. The controller can be uniformly applied on all distributed nodes and guarantees good stability margins, enhanced performance and reduced jitter noise. A 2-dimensional Cartesian mesh network structure is considered without using any feedback loop phase information propagation to eliminate undesirable mode-locked states.
