In this paper, a mathematical model of the electromechanical actuator is established by analyzing various components of it. And system identification method is used to derive the model parameters for the necessary parameters can be difficult to measure with the required accuracy. Based on the mathematical model, a sliding mode controller is designed for the electromechanical actuator. The simulation...
Quadrotor helicopter is an increasingly popular rotorcraft platform for unmanned aerial vehicle (UAV) study. Development of a mathematical model with accurate model parameters for quadrotor is extremely beneficial to control the system. But accurate measurement of numerous vehicle parameters would be especially challenging. In this paper, a system identification method for the quadrotor model parameter...
Gyroplane is becoming popular these days for its characters of security, reliable and simple operation. Modeling is the first step that put mathematical theory into engineering studies such as aircraft stability, control and handling qualities. Considering the variable rotoring speed, propeller, tail aero forces and moment, this paper explores the mathematical model of an unmanned mode gyroplane based...
