2. Optimal Control Model for an Autonomous Underwater Vehicle
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The main goal with this thesis was to develop an optimal control model for anautonomous underwater vehicle (AUV) and evaluate whether reference trackingusing Model Predictive Control (MPC) based on a linear dynamics modeldescribing all six degrees of freedom (DOF) is a suitable method for waypointnavigation. MPC is an advanced receding horizon optimal control method capableof including constraints in the optimization. READ MORE

3. State- and Parameter Estimation for Spacecraft with Flexible Appendages using Unscented Kalman Filters
University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknikAbstract : The problem of system identification for dynamic effects on spacecraft has become increasingly relevant with the surge of agile spacecraft, which must perform large amplitude maneuvers at high rates. Precise knowledge of the state of the spacecraft, as well as of the parameters characterizing its motion, is vital for the design of control algorithms enabling stabilization and pointing accuracy.

5. Vehicle Mass and Road Grade Estimation Using Kalman Filter
University essay from FordonssystemAbstract : This Master's thesis presents a method for on-line estimation of vehicle mass and road grade using Kalman filter. Many control strategies aiming for better fuel economy, drivability and safety in today's vehicles rely on precise vehicle operating information. In this context, vehicle mass and road grade are crucial parameters. READ MORE
