Abstract	Event-triggered control (ETC) is a control strategy in which the control algorithm is executed only when a specific condition is satisfied. Many contributions have been proposed in the ETC literature to reduce the amount of data sent over a communication network. One of the main goals in these methods is reduction of the network bandwidth usage. In this study, a method is proposed to design ET controller which guarantees stability as well as a higher bound on bandwidth requirement. Moreover, the effect of control system on the maximum delay of communication link is explained. Mathematical expression of this effect is presented based on network calculus rules. This yields a method for off-line fair allocation of bandwidth. Furthermore, a new method is proposed to design a robust controller for norm-bounded uncertainty which stabilises the control system and guarantees the bandwidth usage and consequently the network delay. To illustrate the effectiveness of the proposed methods, a case study based on the IEEE 802.15.4 protocol is presented which shows the relationship of controller parameters, network parameters, and the delay.
