In this paper, some improvements of the simple event-based PID controller presented by K-EÅrzén in [2] are proposed. This controller, contrary to a time-triggered controller which calculates the control signal at each sampling time, calculates the new control signal only when the measurement signal sufficiently changes. In the original work ofÅrzén, a safety maximum period is added forcing the control to be recomputed even if the measurement signal remains unchanged. The contribution of this
