Sliding mode control of photoelectric tracking platform based on the inverse system method
摘要： In order to improve the photoelectric tracking platform tracking performance, an integral sliding mode control strategy based on inverse system decoupling method is proposed. The electromechanical dynamic model is established based on multi-body system theory and Newton-Euler method. The coupled multi-input multi-output (MIMO) nonlinear system is transformed into two pseudo-linear single-input single-output (SISO) subsystems based on the inverse system method. An integral sliding mode control scheme is designed for the decoupled pseudo-linear system. In order to eliminate system chattering phenomenon caused by traditional sign function in sliding-mode controller, the sign function is replaced by the Sigmoid function. Simulation results show that the proposed decoupling method and the control strategy can restrain the influences of internal coupling and disturbance effectively, and has better robustness and higher tracking accuracy.

摘要： In this paper, we design a bionic eye platform that includes the hardware and software. Based on the analysis of the structure of the human eyes, we design the mechanical structure which can imitate human eye movement. We design a motor control circuit and data acquisition circuit. In addition, we improve the control system programming and interface design. It has a good performance on object tracking. Finally, we design the PID controller and sliding mode controller to verify the accuracy of smooth tracking.

[IEEE 2018 International Conference on Information Systems and Computer Science (INCISCOS) - Quito, Ecuador (2018.11.13-2018.11.15)] 2018 International Conference on Information Systems and Computer Science (INCISCOS) - Energy Management of a Solar-Battery Powered Fixed-Wing UAV
摘要： In this work, a hybrid solar-battery feeding system is proposed to achieve a constant output power on a fixed-wing Unmanned Aerial Vehicle-UAV. Firstly, a single and hybrid power source configurations for long endurance UAV applications are exposed. Thus, a solar-battery based feeding system with a suitable energy management is proposed. Furthermore, a Maximum Power Point Tracking (MPPT) technique is selected to achieve the maximum efficiency of the solar photovoltaic (PV) array. Besides, Sliding-Mode Control (SMC) is implemented on a cascade control scheme in order to achieve a suitable energy conversion. Finally, the hybrid feeding system performance is analyzed for different solar radiation and load profiles remarking proper dynamic and steady-state responses.
