This paper describes 5-axis centralized feedback control system for a single-rotor helicopter.Optimal control theory is directly applied to 25-state Multiple-Input Multiple-Output (MIMO) analytical linear model of a small-scale unmanned helicopter without decoupling the motion dynamics.The linear Kalman filter is also designed for an estimation of
The Global Positioning System (GPS) has become the most widely used positioning, navigation, and timing system.However, the vulnerability of GPS to radio frequency interference has attracted significant attention.After experiencing several incidents of intentional high-power GPS animed blue lotion topical spray jamming trials by North Korea, South
