Sampled-Data Control with Actuators Saturation

With the rapid development of intelligent instrument and digital measurement, modern control systems tend to be controlled by digital signal processing approaches, i.e. the control input signals are kept constant via a ZOH during the sampling instants and are only allowed to change at the discrete time instants. Thus, sampled-data control problem has been a hot research topic and numerical essential approaches have been derived in the literature, which include three main models: discrete-time model (Zhang et al., IEEE Control Syst Mag, 21:84–99, 2001, [1]), impulsive model (Hu et al., IEEE Trans Syst Man Cybern Part B Cybern, 33(1):149–155, [2]) and input delay model (Fridman et al., Syst Control Lett, 54(3):271–282, [3]).
