Blackbody impedance model

Radioengineering
Models of black anisotropic bodies are proposed, realized by a fine lattice of orthogonal impedance bands with generally variable orientation on the surface. Using flat surfaces and bodies of arbitrary shape as examples, it is shown that the impedance of a black anisotropic body is a complex quantity, the real part of which (resistance) can take both ...

Model Predictive Variable Impedance Control of Manipulators for Adaptive Precision-Compliance Tradeoff

IEEE/ASME Transactions on Mechatronics, 2023
Impedance control (IC) is widely used in contact-rich manipulator tasks since it provides manipulators with both operation precision and contact compliance, and trades them off by impedance parameters.
