On the Passivity Based Impedance Control of Flexible Joint Robots [PDF]

, 2008
In this paper, a novel type of impedance controllers for flexible joint robots is proposed. As a target impedance, a desired stiffness and damping are considered without inertia shaping.

Impedance and impulse response measurements using low-cost components [PDF]

The Journal of the Acoustical Society of America, 1982
A thin 27-mm-o.d. disk transducer (from Radio Shack 273-060 signaler) is RTV sealed to the end of a measurement tube whose 15 mm i.d. not only approximates the transducer disk's nodal circle but also the i.d. of a clarinet, sax, or trumpet mouthpiece. A 10-mm-o.d.

Application of Impulse Response Characteristics in Rail-ground Transition Resistance Measurement

Chengshi guidao jiaotong yanjiu
Objective The stray current harm in urban rail transit lines is increasingly non-ignorable. Stray current is not easy to be detected, and the amount of the rail-ground transition resistance is a crucial factor affecting stray current.
