摘要：

In this work, the problem of designing emulation based stabilizing event-triggered state-feedback controllers for nonlinear rational systems is addressed by means of a weighted relative error measure in the trigger function. It is shown that the proposed event generator does not lead to a Zeno behavior for the class of nonlinear rational systems. Considering a differential algebraic representation of the nonlinear system and applying the Lyapunov theory, a convex optimization problem in terms of LMI constraints is derived to ensure regional asymptotic stability of the origin while designing the trigger function parameters in order to minimize the control updates. Numerical experiments illustrate the approach showing its potentials as a tool for designing event trigger functions.
