Optimized Altitude Control for Quadrotor UAV in Virtual Environment

Quadrotors offer many interesting features and have great potential to be used in many social applications. Unfortunately, due to its nature as an underactuated system, it can be made stable by itself. Hence, such a control strategy is required. This paper presents the optimized PID controller with Firefly Algorithm (FA) for quadrotor in virtual environment. The results verify that the optimized PID controller succeeds to regulate the altitude of quadrotor in the real physics-like of virtual environment.
