Control: Event-Triggered Control (Lectures on Advanced Control Systems)

Event-triggered control is a control strategy in which signals exchanged between a processor and a system (or between two systems) when triggering events occur. It relaxes standard periodic information exchange in order to reduce the communication burden. This video presents a basic introduction to event-triggered control. Note A fact that I forgot to mention at time 10:40 of this video: To claim that the closed-loop system is bounded, mu should be chosen such that 1-mu*||PB||_2^2 is positive. Since mu is an arbitrary positive constant resulting from Young's inequality, we can always ensure that 1-mu*||PB||_2^2 is positive by judiciously choosing mu. One choice is mu=0.5/||PB||_2^2, which yields 1-mu*||PB||_2^2=1-(0.5/||PB||_2^2)*||PB||_2^2=0.5.
