报告摘要：We develop cooperative estimation and control algorithms in uncertain communication environment. For distributed averaging with random graphs and noises, sufficient conditions in terms of uniformly conditionally joint connectivity of random graph sequences are given to ensure mean square and almost sure consensus. For consensus+innovations algorithms we prove that the algorithm gains can be designed properly such that all agents’ estimates converge to the real parameter in mean square if the observation matrices and communication graphs satisfy the stochastic spatial-temporal persistence of excitation condition. For cooperative stabilization of linear systems with partially measurable states and finite data rate, quantized-observer based communication protocols and certainty equivalence principle based control laws are proposed to characterize the inter-agent communication and cooperative control in an integrative framework. For stochastic consentability with multiplicative noises, explicit sufficient conditions are deduced in terms of unstable eigenvalues of agent dynamics, network graph and channel noise intensities.
