A ship course controller is designed for Norrbin nonlinear ship mathematical model with matching uncertainty. Combining the backstepping algorithm with the nonlinear damping algorithm to design controller, the nonlinear damping is used to cancel the uncertainty. The integral item is introduced in the design to improve the performance of the controller. Now, general ships can only use the electric gyrocompass to measure the course angle, but they have no equipments to measure the angular velocity, so in this article another ship course controller of output feedback is designed for Norrbin nonlinear ship, firstly the angular velocity is estimated by the observer and then the ship course controller is designed.

In order to ensure the precision and reliability, this paper designs the GPS/Loran C/SINS/AHRS integrated system. In this integrated system, the self-adaptive federated Kalman filter is introduced to revise strap-down inertial navigation system; the heading angle attitude and heading reference system is used to ensure the convergence of heading angle; and the coordination transformation for Loran C is applied to eliminate the constant error of Loran C.

We cannt get result on how to change course and speed to make collision avoidance, this can help little on collision avoidance decision.The article aims at the default on Radar simulator and implements the standard result on Radar simulator by making use of MCU.the main production is below:First, we calculate how to chang course and speed on the destine point by MCU. We get the new course and new speed on the destine point,we get the point to resume original course and speed, we get the distance and azimuth to resume original course and speed on given course and speed, the six essential: DCPA, TCPA, distance, azimuth,real speed and real course.

However, due to disturbances caused by sea wind, sea wave, sea flow and some other uncertainties such as variance of ship physical parameters, how to control autopilots properly is a very difficult problem. An autopilot based on fuzzy logical control is proposed to make a ship follow the virtual course, which is calculated from real course and track deflection.

Fluxgate sensor inducts the environment magnetic field, outputs the compass course signal to the CPU system. This signal then is transformed into digital signal. CPU processes it and then gains compass course. When use rotary mathod to measure the deviations, CPU first collects timed the compass course come from the Fluxgate sensor, then calculates automatically their deviations and the correspondent coefficients. Based on all this, CPU can calculates out the real-time magnetic course or the real-time ture course, then sents them to display on the digital displayer.
