A Self-tuning Nonlinear PID Controller for a Three-Thruster Remotely Operated Underwater Vehicle
conference contribution
posted on 2023-05-23, 08:09 authored by Le, KD, Hung NguyenHung Nguyen, Susantha RanmuthugalaSusantha RanmuthugalaRemotely Operated Vehicles (ROV) are widely utilized within the maritime industry, including oil and gas exploration, security, and in environmental protection duties. However, designing proper controller systems for ROVs is not an easy task due to the nonlinear dynamic effects and environmental disturbances. This paper describes the development of a self-tuning nonlinear PID controller for an observation class ROV consisting of three thrusters. The proposed algorithm differs from conventional PID control systems, and mimics the principle of neural cells whose parameters have the ability to adapt to the uncertainty of the controlled system. To verify the effectiveness of the nonlinear PID control algorithm, a mathematical model of the ROV incorporating hydrodynamic coefficients obtained through Computational Fluid Dynamics (CFD), is used to compare the performance of a conventional PID controller to that of the proposed nonlinear PID controller.
