In this chapter, we propose an easily-implemented switched sampled-data (SD) control strategy which may enhance the stability as well as dynamic performance. Regarding the stability issue, we will show that the use of the switched SD control strategy allows to enlarge the stability bound on the sampling period. As a consequence, a controlled task can be stabilized with less system resources by using the switched SD controller. We will also study the dynamic performance of a DCES with the switched SD control. An optimization method is proposed to optimally set the switching parameter of the switched SD controller. Thus, given a sampling period, we may obtain the optimal performance index through an appropriate setting of the switching parameter. We will show that the switched SD control may lead to a much better performance index than the standard single-sampling control. In other words, with the same utilization of computation and communication resources, the dynamic performance of a controlled task may be considerably enhanced by using the switched SD control.
