The invention discloses a
video tracking control method and device for a non-linear moving target based on adaptive
sliding mode control, which are suitable for accurate tracking of a dynamic target. The
system is composed of a visual sensing module, a main control module and an execution mechanism, the visual sensing module collects position information of a target object in real time and transmits the position information to a main control
chip through
serial port communication, the main control
chip calculates the error between the target position and the current position of the
system and the error change rate, and a sliding mode surface is designed based on
sliding mode control. Meanwhile,
sliding mode control parameters are dynamically adjusted in combination with a self-
adaptive control algorithm, so that the robustness of the
system to uncertainty and external interference is enhanced, and meanwhile the chattering phenomenon is restrained. A stepping
motor control signal is optimized by introducing a dynamic acceleration and deceleration
algorithm, so that control smoothness and response precision are ensured, and real-time accurate tracking of a target object is realized. The method has strong robustness, high dynamic performance and control precision on the premise of not depending on a target kinematic model, can be widely applied to the fields of unmanned aerial vehicle tracking, intelligent monitoring,
robot vision and the like, and effectively solves the problems of easy buffeting, response
hysteresis, insufficient control precision and the like during nonlinear target tracking in the prior art.
