Time‐triggered intermittent control of continuous systems

Abstract
Abstract For intermittent control, its control signal is updated in a continuous manner on control time intervals. To overcome the limitation, time‐triggered intermittent control (TIC) is presented for the first time in this article. In our work, based on a new time‐triggered mechanism, the mathematical description of TIC is put forward and a TIC system is modeled. Different from the traditional time‐triggered mechanism, the new time‐triggered mechanism just allows the partial sampled data to be transmitted. Due to different structures of the TIC system, a mixed Lyapunov functional is introduced to obtain a general stability criterion. As a result, a stabilization criterion of continuous systems with TIC is deduced and two methods to design TIC are proposed. Further, comparisons between TIC and sampled‐data control (SC) are made. Finally, an example is given for illustration.
