RISRobust Composite Control for Singularly Perturbed Systems With Time-Varying Uncertainties
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A two-time-scale linear system with uncertain time-varying parameter is to be stabilized. A class of robust composite controls is proposed. The control renders the system practically stable ...
Real-time Compensation for Time-variant Volumetric Errors on a Machining Center
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An error compensation system has been developed to enhance the time-variant volumetric accuracy of a 3-axis machining center by correcting the existing machine errors through sensing, metrology, ...
A Fast Electro-Optical Sensing System for Measuring Thermal Response of a Rotating Roll Without Generating Contact Noise
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A non-contact sensing system has been developed to measure the temperature response of a rapidly rotating roll under spray cooling encountered in metal rolling processes. A thin-film sensor with ...
Application of Finite Element Analysis for Determination of Load Share, Real Contact Ratio, Precision of Motion, and Stress Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A loaded gear drive with point contact between tooth surfaces is considered. The principal curvatures and directions at a current point of tangency, the contact paths on tooth surfaces, and ...
