Line impedance estimation provides crucial information for power-line communication (PLC), power quality estimation, and grid-connected power electronics applications. Online techniques are particularly useful as the line impedance is time-dependent. This work uses a phase-controlled switch to generate a turn-on transient, which provides information ...

Contact impedance estimation for robotic systems
IEEE Transactions on Robotics, 2005In this paper, the problem of online estimation of the mechanical impedance during the contact of a robotic system with an unknown environment is considered. This problem is of great interest when controlling a robot in an unstructured and unknown environment, such as in telemanipulation tasks, since it can be easily shown that the exploitation of the ...

A Method for Estimating the Utility Harmonic Impedance Based on Semiparametric Estimation
IEEE Transactions on Instrumentation and Measurement, 2021Estimating the utility harmonic impedance of a point of common coupling (PCC) is of significance to harmonic emission level evaluation. The most existing methods for estimating the utility harmonic impedance are based on the assumptions that the background harmonic fluctuates in a small range, and the customer harmonic impedance is much larger than the

Estimation of PP‐ wave ray impedance from elastic impedance
SEG Technical Program Expanded Abstracts 2011, 2011Theoretical evaluation of elastic impedance (EI) and ray impedance (RI) reveals that RI has a more reliable dimension and is less sensitive to errors than EI. In this paper, a new measurement (R I) is proposed to estimate ray impedance from the elastic impedance derived by existing techniques.

Estimation of load impedance in a power system
Ninth International Conference on Harmonics and Quality of Power. Proceedings (Cat. No.00EX441), 2002This paper describes a novel technique for measuring power system impedance back to source. The technique employs a power electronic converter which injects a voltage transient onto the network via an inductor. The resulting current is correlated with the disturbance voltage to determine the impedance.

Environment estimation for enhanced impedance control
Proceedings of 1995 IEEE International Conference on Robotics and Automation, 2002Impedance control is a popular method of controlling the dynamic response a robot has to external forces. The advantage of such a control paradigm is the ability to manipulate in both unconstrained and constrained environments. Unlike hybrid control methods that attempt to control forces and motions in orthogonal directions, impedance control consists ...

Impedance-effects in capacity estimation
ZOR Zeitschrift für Operations Research Methods and Models of Operations Research, 1992Summary: Formulas for the capacity of an unsignalized intersection for traffic streams which are subordinated to two or more streams of higher priority are developed. The case of only two conflicting streams analysed by \textit{J. C. Tanner} [Biometrika 54, 657-658 (1967)] is extended.
