Automatic Control of a Submersible.

Abstract

Multivariable control theory is used to design a controller for a modified drooping stern turning submersible. The procedure used is based on the LQG/LTR methodology. The controller is designed from a linear model and tested for performance on a nonlinear system model. Control variables are: turning velocity, roll, and pitch. The resulting controller successfully minimizes roll and pitch for a turning submersible. (Author)
