Concerned with the control precision of UAV s flight path control system,an improved method for UAV s flight path automatic control is presented based on extended Kalman filter.

Based on the requirements for precision flight path control during the carrier-based aircraft oncarrier landing approach,two different flight path control systemswind-referenced flight path control system and inertia-referenced flight path control system-are designed by means of a system integration design approach,utilizing existing flight control effectors.

The design of autonomous flight tracking control system for helicopter is an important issue.

The control of ship movement is characterized by its strong non-linear, uncertain, large inertia, large delay and slow time-varying, with additional hydrodynamic disturbances and noises, all of which make the track control more complicated.

Adaptive backstepping designs for tracking control of underactuated ships with parameter uncertainty;

This paper put forward the tracking control method which is valuable for wide application in marine surveying.

In this paper,based on analyzing operation Principle of yawing indication method,three methods which judge relative position of survey ship and scheduled survey line are advanced,and the calculation methods of course correction variable is completed,which provide the theory base for tracking control.
