Abstract

In this extended abstract, a stability certificate is presented for sampled-data implementations of static output feedback control with asynchronous sensor sampling and zero-order-hold actuator updates, given continuous-time twoinput-single-output linear time-invariant system dynamics. The approach involves structured integral quadratic constraint (IQC) based robustness analysis, given individual bounds on the uncertain sample and two update intervals involved, and relationships between these. New IQCs for an operator that depends on multiple time-varying delays are also presented.
