ABSTRACT

This chapter discusses periodic event-triggered control (PETC) strategies, their benefits, and two analysis and design frameworks for linear and nonlinear plants. It focuses on approaches to PETC that include a formal analysis framework, which apply for continuous- time plants and incorporate intersample behavior in the analysis. The chapter explores PETC as a class of event-triggered control (ETC) strategies that combines the benefits of periodic time-triggered control and event-triggered control. In ETC, the control task is executed after the occurrence of an event, generated by some well-designed event-triggering condition, rather than the elapse of a certain fixed period of time, as in conventional periodic sampled-data control. The PETC strategy is based on the idea of having an event-triggering condition that is verified only periodically, instead of continuously as in most existing ETC schemes. There is a strong need for systematic methods to construct PETC strategies that appropriately take into account the features of the paradigm.
