Research on the control strategy of unmanned tracking ship based on GPS

In this paper, GPS unmanned tracking ship which is a successful improvement of traditional artificial measurement of underwater topography is introduced. Modified PID and Bang-Bang algorithm are applied in the speed control and direction control of GPS unmanned tracking ship. By using the new algorithm, the surveying work can be accomplished automatically. Through the comparison of using modified PID algorithm or not in the track and average speed of the Tracking Ship, we can conclude that the improved scheme can be more efficient, more economical and more secured in accomplishing the surveying work of measuring the data of underwater topography than traditional artificial scheme.
