N2 - We study networked control of linear discrete-time systems using self-triggered strategies to reduce the amount of communication between the plant and the remote controller. At each transmission, the controller determines the next transmission time in advance based on the current state. We propose three self-triggered strategies which guarantee control performance based on a quadratic cost function. They have different characteristics with respect to the on-line computation load for finding the transmission times. Through a numerical example, we illustrate the effectiveness of the three strategies and, in particular, demonstrate the tradeoffs between computation loads and transmission frequencies.
