Interfacing Fast Nanopositioners to Track-Following Servos Leveraging the power of PI’s unique Fast/Precise Dual Interface for head test
نویسنده
چکیده
Background Sub-nanometer precision and accuracy plus high positioning bandwidth have made piezo nanopositioners essential for track profiling applications in spin-stand applications. However, (1) relentlessly advancing areal density requirements and (2) the advent of patterned media raise new issues for spin-stand integrators. These emerging needs require that the nanopositioner perform within the spin-stand’s track-following servo loop, requiring extremely responsive positioning with highly deterministic real-time communications.

Harmonics Estimation in Power Systems using a Fast Hybrid Algorithm
In this paper a novel hybrid algorithm for harmonics estimation in power systems is proposed. The estimation of the harmonic components is a nonlinear problem due to the nonlinearity of phase of sinusoids in distorted waveforms. Most researchers implemented nonlinear methods to extract the harmonic parameters. However, nonlinear methods for amplitude estimation increase time of convergence. Hen...
