Event-triggered impulsive control is a control strategy that combines the benefits of traditional control theory with the advantages of impulsive control. It is particularly useful for systems that are sensitive to delays and have non-linear dynamics. In ETIC, a controller is designed to trigger an action at a specific event, such as the occurrence of a disturbance or the reaching of a threshold. This action is then used to adjust the system's state and control its behavior. The fractional order system that we will simulate is modeled using the Caputo fractional derivative, which is a well-known method for modeling non-linear systems. The s...
