內(nèi)容摘要：
This talk considers the exponential stabilization for reaction-diffusion systems (RDSs) by means of intermittent boundary control. For the case where all system states are available, a state-dependent intermittent boundary controller is designed, and a sufficient condition ensuring the exponential stability of RDSs is presented by employing spatial integral functional method and Poincare's inequality. For the case where system states are not fully accessible, a boundary observer is proposed to estimate the system states, and an observer-based intermittent boundary controller is provided such that the considered system is exponentially stable. Furthermore, an observer-based intermittent boundary controller is designed for the robust exponential stability of uncertain RDSs. Simulation examples are presented to show the effectiveness and potential of our theoretical results.
