Binary sequence based dynamic scheduling and control co-design for cyber-physical systems

In this paper, the MRBS-based dynamic scheduling and control co-design is proposed for the cyber-physical systems (CPSs) to solve the capacity limitation of the wireless network. The analytical most regular binary sequences (MRBSs) are used as the scheduling function, which leads to CPSs as the non-uniform sampled-control systems caused by the non-uniformly distributed ‘1’ and ‘0’ of the MRBS. By using the MRBS-based dynamic scheduling strategy and piecewise constant controller structure switched according to the segment of MRBS, a scheduling and control co-design algorithm is proposed for the CPSs to simultaneously decide the controller gain and the parameters of MRBS-based dynamic scheduling strategy, which can guarantee the stability of the CPSs suffered to communication conflicts and asynchronous controller gain switching. A numerical example is given to demonstrate the effectiveness of the proposed co-design method.
