Self-triggered control for communication reduction in networked systems

We study networked control of linear discrete-time systems using self-triggered strategies to reduce the amount of communication. 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 computation load for finding the transmission times. Through a numerical example, we demonstrate the tradeoff between computation loads and transmission frequencies.
