Robust Sampling Switching Control of Complex Dynamic Networks Considering on Actuator Saturation
With the development of computer and network technology,research on robust sampling switching control of complex dynamic networks receives widespread attention.The problem of aperiodic sampling control of complex dynamic networks with uncertain switching under actuator saturation is discussed.Since the upper limit of the sampling interval is limited by the dwell time,asynchrony issues between sampled data controller mode and system mode may be caused by subsystems switching within the sampling interval.By considering the sampling interval without switching and the sampling interval with switching,parameter-dependent Lyapunov closed-loop functionals are constructed respectively.Under the definition of average residence time and with the help of the constructed functional,the mean square exponential stability criterion of the uncertain switching complex dynamic networks error system is given.In addition,based on the stability criterion,a new asyn-chronous aperiodic sampling controller is designed for the complex dynamic networks of uncertain switching with actuator saturation.According to the proposed stability conditions and aperiodic sampling controller design method,the exponential synchronization of the uncertain switching complex dynamic networks with the target node is guaranteed.Finally,the effectiveness of the proposed method is verified by comparing an example of Chua's circuit with other similar methods,and it also shows that the maximum allowable sampling interval ob-tained by the proposed method is larger.
