Study on the Position Control System of the Float Chamber using Air Control

The paper is that study method to reduce bad influence that act to the floating fish cage by effect of environment in sea. Fish cage is controlled buoyancy using air control. According to marine environment, it is descend automatically to set-up depth and rise on the surface of the sea. The paper is the preceding research for a practical application. The fish cage simplified with the spherical float body. Then a control algorithm and a program developed by the experiment. And we did modelling by bond graph technique, and controlled by the practical reference model for PID control.
