Autopilot Design for an Autonomous Vehicle under 6-Degree Motion

Autopilot technique in fluid dynamics is value able from last decade due to under water environmental activities, include navigation, control, defense, communication. Autonomous under water vehicle stability criteria is tough task to achieve due to involvement of fluid dynamics. Wave encounter with the head of submarine cause nonlinearity in AUVs movement. In this paper we become familiar with the techniques of analysis& controller design for AUVs by implementation of Control Law Design (CLD) possessing Pole Placement Technique (PPT).
