This paper deals with the implementation of an adaptive speed controller applied for two electrical machines coupled by a long shaft. The main parts study are synthesis neural and hardware using low-cost system based on STM Discovery board. framework between control system, power converters, motors is established ARM device. A radial basis function network (RBFNN) used as controller. net coeffi...

Robots promise to enhance minimally-invasive surgery, but flexion of the thin instrument shaft introduces error into models of the robot kinematics. Visual or electromagnetic tracking of the instrument tip provides correct forward kinematics, but uncertainty in shaft bending and port location leaves residual errors in inverse kinematics. These errors can cause incorrect motions that preclude th...

The following describes experimental methods for characterizing ice hockey pucks and sticks at game-like speeds. Pucks were characterized according to their coefficient of restitution (COR) and dynamic stiffness (DS) for different brands, speeds, and temperatures. The COR provided a measure of the puck’s elasticity, while the DS provided a measure of puck hardness. At room temperature, puck COR...

An augmented Kalman filter for torque estimation in marine propulsion-system drive trains is presented. Propeller and motor excitations responses are estimated based on a dynamical model of the system inboard shaft measurements. Input affecting propulsion systems signals whose statistical properties vary between finite time intervals. Hence, this paper, characterized as quasi-stationary with bo...

In this paper torsion of hollow Poroelastic shaft with Elliptical section is developed. Using the boundary equation scheme. It looks for a stress function where satisfied Poisson equation and vanishes on boundary. It also analyzed stress function and warping displacement for the hollow elliptical section in Poroelastic shaft. At the end, the result of elastic and poroelastic shaft in warping di...

The construction of a backstepping-sliding mode control using high-gain observer's neural network for torque estimation is presented in this research. correctness the load data crucial to solving two-mass system issue. article suggests radial basis function topology handle estimation. When non-rigid drive shaft present, predicted value merged with ensure speed tracking performance. closed-stabi...

In this study, an analytical model is developed to study crack breathing behavior under the effect of crack location and unbalance force. Crack breathing behavior is determined using effectual bending angle by studying the transient change in closed area of the crack. The status of the crack of a balanced shaft is symmetrical about shaft rotational angle and the duration of each crack status re...
