State-dependent Riccati equation based controllers are becoming increasingly popular because of having attractive properties like optimality, stability and robustness. This paper focuses on the design of a roll autopilot for a fin stabilized and canard controlled 122mm artillery rocket using state-dependent Riccati equation technique. Initial spin is imparted to rocket during launch and it quic...

Many types of vehicle control systems can conceivably be developed to help drivers maintain stability, avoid roll-over, and customize handling characteristics. A lack of state and parameter information, however, presents a major obstacle. This dissertation presents state and parameter estimation methods using the Global Positioning System (GPS) for vehicle dynamics control. It begins by explain...

The final hot strip profile is a superposition of the roll initial crown, the roll bending and flattening crown, the roll wearing crown and the roll thermal crown. In this research, linear regression models are proposed to predict the roll force, the roll wearing crown and the roll thermal crown using experimental data provided by Mobarake Steel Complex (MSC). The short beam theory based on ela...

The oscillating-water-column (OWC) spar-buoy is a type of wave energy converter that may exhibit undesirable large roll and pitch amplitudes caused by dynamic instability induced parametric resonance. occurrence this phenomenon not only reduces the power extraction but significantly increases structural loads on buoy, turbine rotor mooring system. paper compares resonance behaviour two configur...

In this study dynamic responses of a 10 MW offshore wind turbine supported by multi-body floating platform that consists wide cylindrical and ballast body suspended six tendons are analyzed predicted for different tendon breakage scenarios. A newly-developed validated fully coupled numerical tool (F2A) based on AQWA FAST is used to perform aero-hydro-servo-elastic analysis the (FOWT). The resul...
