This paper analyzes the possibility to induce residual compressive stresses utilizing deep rolling in a long, slim steel workpiece that is profile ground and resembles linear guide rail. These intentionally caused at side surfaces of are intended counteract distortion due V-groove rail induced by grinding. A finite element model was prepared based on initial state workpiece. The amount respecti...

The induction motors are characterized by complex, highly nonlinear and time-varying dynamics, and hence their speed control is a challenging engineering problem. The advent of vector control techniques has partially solved induction motor control problems, but they are sensitive to drive parameter variations and performance may deteriorate if conventional controllers are used. By exploiting th...
