Abstract: A technique to synthesize optimal excitations for dynamic testing is presented. A quadratic function of the frequency response at modeled degrees of freedom of the test object is employed as ...

Abstract: In this paper the classical time domain design problem of position servoactuators having proportional plus derivative (PPD) error controllers is reconsidered. Control system stability is represented ...

Abstract: Several shortcomings of available standards, regulatory guides, and review plans for seismic qualification testing are identified. A rational test nomenclature is proposed. A standard test is ...

Abstract: A control scheme is presented for trajectory following with robotic manipulators. The method employs a feedforward torque for gross compensation and adaptive feedback gain scheduling for correcting ...

Abstract: This paper presents a methodology for the design evolution of engineering systems, with a mechatronic emphasis. The developed approach specifically integrates machine health monitoring and an ...

Abstract: Required response spectra (RRS) are commonly used as dynamic-test specifications in product qualification. RRS specification for a product is normally developed by considering the operating environment ...

Abstract: This paper describes the development of a joint torque sensor for the second direct-drive manipulator at Carnegie-Mellon University (CMU DD Arm II). The approach taken is to develop the sensor ...
