Abstract
This paper studies observer-based output feedback consensus control of networked homogeneous systems in the presence of unknown bounded actuator and sensor delays. A transport hyperbolic partial differential equation (PDE) is used to describe
the dynamics of the delay state, and then a distributed observer on the basis of the estimate delay state and relative output information is designed to estimate the neighborhood consensus error. Predictor-based consensus protocols are proposed by
utilizing the observer state and the estimate delay state. Lyapunov-Krasovskii functions are explicitly constructed to analyze system stability, and the delay mismatch robustness of the consensus protocols is proved. Simulation results performed on low-Earth-orbit satellite formation flying are presented to illustrate the effectiveness of the proposed scheme.
