Technosys Systems

Overview:
The four-rotor hover vehicle consists of motors with airscrews, encoders, drive modules, motion controllers and slip rings, etc. It is a highly coupled multiple degrees of freedom system. Different flight controls such as elevation and depression, inclination and hovering of the vehicle can be achieved. The system is suitable for undergraduates, postgraduates and control theory researchers to carry out verification and research of control theory such as optimal control, robust control, etc. The four-rotor hover vehicle is powered by the 4 airscrews of the motors placed at the gumball shaft. The front, left and right motors drive the corresponding airscrews to fulfil the elevation and depression of the vehicle, the left and right motors drive the corresponding airscrews to overturn the vehicle, while the rear motor drives the corresponding airscrews to realize the navigation of the vehicle. The 3 encoders which are installed on the platform detect the different aviation statuses of the vehicle and form a closed loop system, thus fulfil precise positioning of the elevation and depression, tilting and hovering of the vehicle. Slip rings are installed in the base of the vehicle so that the wirings will not tangle up when the vehicles rotate freely. It also helps to reduce friction.

Automatic Control Experiment Box
The automatic control experiment box uses a semi-physical simulation to achieve an understanding of the principles of automatic control. The semi-physical simulation is to connect the mathematical model, the solid model and the actual equipment of the system to form a simulation system. When simulating this system, the physical intervention in the analog loop requires that the simulation be performed on-the-fly. The simulator must acquire dynamic input signals under the conditions of synchronization with the real system and generate dynamic output responses in real time. The experiment box is free to design a variety of circuits with various components, and the Matlab software platform can be used to simulate experimental phenomena and results in real time. The experimental box design is compact and suitable for large-volume placement in the laboratory to meet the experimental needs of the team.
