The optimal event-based control of parachute opening problem II: A case study

We propose an finite time optimal event-based controller associated with an optimized strategy of parachute air drop in a rescue mission in order to minimize the drop interval to ensure a fast and accurate landing while a safe landing speed must be guaranteed. The idea is to determine an optimal instant to trigger the event-based controller. The design takes several steps to simplify the optimization via the tools of integration, penalty function and steepest descent algorithm. The result shows that the proposed controller yields the best performance among the non-optimized ones.
