For manned drive for the rubber tram to track virtual tracks can easily lead to driver fatigue problems, on the basis of the visual navigation, an automatic steering control method based on the model predictive control is proposed. In the paper, Firstly, the automatic steering control principle based on visual navigation vehicle is introduced; then, the automatic steering predictive controller is...
In this paper, an offline flight planner that computes an efficient coverage trajectory for a quad-rotors UAV is presented. The planner consists of three steps: mission definition, automatic path planning and trajectory generation. The proposed planner, as a useful tool, allows an UAV operator to easily define and generate a coverage trajectory for any specific task. The resultant trajectory can be...
We have proposed a current observer-based induction motor speed sensorless vector control system which is composed in a rotating reference frame. The characteristic improvement of this system is discussed by taking into account iron loss, stator resistance identification, current low-pass filter and speed estimation low-pass filter. The stability of the system has been investigated by the trajectories...
