A novel modeling method for forward-flyback converter and investigating proper design with guidelines to eliminate right half plane zeros [PDF]

open access: yesAUT Journal of Electrical Engineering
The main advantages of the flyback converter are the simple topology and the isolation of the output from the primary, which is useful for cases where a compact design is required.

A Calibration Method Based on Transfer Function Extraction for Cartesian Vector Modulator

open access: yesIEEE Access, 2020
In this paper, a calibration approach based on transfer function extraction for the Cartesian vector modulator (VM) is presented. Three kinds of VM models-the ideal VM model, the frequency-dependent VM model and the modified frequency-dependent VM model,

Improved Prediction Model of the Friction Error of CNC Machine Tools Based on the Long Short Term Memory Method

open access: yesMachines, 2023
Friction is one of important factors that cause contouring errors, and the friction error is difficult to predict because of its nonlinearity. In this paper, a prediction model of the friction error of a servo system is proposed based on the Long Short ...

Rational inner functions in the Schur-Agler class of the polydisk [PDF]

open access: yes, 2010
Every two variable rational inner function on the bidisk has a special representation called a transfer function realization. It is well known and related to important ideas in operator theory that this does not extend to three or more variables on the ...
