This talk relates to the analysis of L2 stability and performance for networks of dynamical systems involving asynchronous sampled-data links. An input-output approach will be presented in terms of integral quadratic constraints (IQCs). These are used to encapsulate the structured uncertain time-varying delay associated with the link class considered. In particular, the IQCs for a link are parametrized by bounds on the variable inter-sample interval at the source and the relative asynchrony of zero-order-hold updates at the sink. Verification of the resulting analysis conditions for network stability and performance can be posed as a finite-dimensional convex optimization problem.
