Title:
DEVICE, SYSTEM, AND METHOD FOR BUOYANCY CONTROL LAGRANGE CAMERA PLATFORM
Document Type and Number:
Japanese Patent JP2020032996
Kind Code:
A
Abstract:
To provide a buoyancy control Lagrange camera platform capable of accurately controlling to a specified depth.SOLUTION: A device for buoyancy control Lagrange camera platform is composed of a buoyancy engine subsystem and a camera subsystem 127 including: a buoyancy engine subsystem 101 including a pressure transducer; the pressure transducer connected to a buoyancy engine controller; the buoyancy engine controller composed to command to the buoyancy engine by using an adaption PID control system for controlling engine volume installed with a gains scheduler composed integrally with a liner control actuation point with a prescribed parameter, the gains scheduler instructing a buoyancy engine controller parameter on the basis of the selected actuation point and the buoyancy engine controller commanding a buoyancy engine adjustment until the platform achieves a desired depth.SELECTED DRAWING: Figure 1
