Dynamic modeling, control aspects and model predictive control of a parafoil and payload system

Creator:: Slegers, Nathan J.
Abstract:: Control issues are investigated for a parafoil and payload system with left and right parafoil brakes used as the control mechanism. It is shown through dynamic modeling and simulation that parafoil and payload systems can exhibit two basic modes of lateral control, namely, roll and skid steering. Using a small...

Computer assisted design of planar workholders

Creator:: Chancharoen, Ratchatin
Abstract:: There are many situations in which contact between two bodies is at a single point so there can be no tensile (force). This form of contact only provides a single degree of restraint, and is defined as a unidirectional point contact. The analysis of Reuleaux shows that four suitably placed...

Kinematic analysis of walking machine foot trajectory

Creator:: Su, I-chih
Abstract:: A method to design foot trajectory in Cartesian coordinates for a six-leg walking machine is presented in this thesis. The walking machine is based on the geometry of the darkling beetle. The walking procedure developed by Y.S. Baek is introduced first to provide step length and leg swing time for...

Kinematic analysis of legged system locomotion on smooth horizontal surfaces

Creator:: Baek, Yoon Su
Abstract:: This thesis presents a model of legged locomotion in which position and velocity of body are directly controlled by positions and velocities of feet. One central relationship between foot acceleration, leg stroke and body velocity is developed. Procedures for determining all parameters of a step sequence including periods of constant...

Two projectiles connected by a flexible tether dropped in the atmosphere

Creator:: Frost, Geoffrey W.
Abstract:: This study investigates the atmospheric flight dynamics of a munition system and the effect of a tether reel resistance mechanism for limiting the impact that the unreeling process has on the munition system. The munition system consisting of two projectiles connected by a tether line is released from an aircraft...

Robust lateral pulse jet control of an atmospheric rocket

Creator:: Burchett, Bradley Thomas
Abstract:: Uncontrolled direct fire rockets exhibit high impact point dispersion, even at relatively short range, and as such have been employed as area weapons on the battlefield. In order to reduce the dispersion of a direct fire rocket, feedback control is employed to fire short-duration solid rocket pulses mounted near the...

Lateral pulse jet control of a direct fire atmospheric rocket using an inertial measurement unit sensor system

Creator:: Jitpraphai, Thanat
Abstract:: Impact point dispersion of a direct fire rocket can be drastically reduced with a ring of appropriately sized lateral pulse jets coupled to a trajectory tracking flight control system. The system is shown to work well against uncertainty in the form of initial off-axis angular velocity perturbations as well as...
