Robust Attitude Control of Helicopters with Three-Degree Freedom Based on Intermittent Event-Triggered Mechanism

In the field of widely used helicopter, this paper studies whether helicopters with three-degree freedom (3DOF helicopters) have a new control method stable attitude. Therefore, two research methods are adopted. One is to use intermittent control, so as achieve stability in short time without its inputting. The other find and update needed meet next through event-triggered mechanism. A theorem given prove feasibility these methods, Lyapunov’s second law also applied analyze model designed for robust attitude control. Besides, we linear matrix inequality solver solve feedback gain controller theorem. Finally, MATLAB simulation, system error state tends zero under which highlights advantages communication few times thus achieving simulation goal.
