Abstract

We propose an event-triggered control method to a ball and beam system with a switching logic based on αϵ-mapping. Our proposed controller has two scaling factors - α and ϵ. We analytically show that there is a tradeoff relation between the output convergence speed to a reference point and interexcecution times, and this relation is characterized by using α and ϵ factors. This characterized feature is called αϵ-mapping. Then, based on the αϵ-mapping, we present a switching algorithm for balanced control performance in terms of the convergence speed and interexecution times. The validity of our control method is demonstrated through the experimental results.
