Abstract

The UAV without control surface (UAV) proposed in this paper uses the propeller driven by four electric motors as propulsion and attitude control. The UAV can take off and land vertically (VTOL), but the control of propeller is a particularly complex problem from hovering to cruise flight. A novel control algorithm using optimal estimates similar to multipurpose linear quadratic regulator (LQR) is suitable for the latest developments. One of the technologies can generate the transformation control input available for a time-varying system model, which will be used by aircraft pilots to provide the necessary control signals for UAV propellers. As a result, traditional trained pilots can control this novel UAV without additional training. In addition, it can be predicted that the general control algorithm can be used for autonomous control of UAVs in the future, allowing the autonomous development of novel control strategies to control the required UAVs.
