ABSTRACT
Typically, the traditional event-triggered control methods operate based on some designed triggering conditions. So, they are controllers with memory because they need to store the past state or output values for checking the triggering conditions to update control inputs. In this paper, we suggest a zero-order-hold triggered control method for a class of approximate feedback linearized systems with the pre-specified interexecution times. Since our proposed control method does not require any triggering condition, it is naturally a memoryless control method. Moreover, we do not need to show the avoidance of the Zeno behavior because the positive lower bound of interexecution times is guaranteed by default. We analyze the system stabilization with our control method and also provide a design rule to adjust the control performance in terms of the convergence speed and number of control input updates. We illustrate the validity of our control method via two examples.
