...Shirin Hassanzadeh Darani; Payam Rabbanifar; Mahmood Hosseini Aliabadi; Hamid Radmanesh Purpose The purpose of this paper is to present a new system frequency response model with participation of wind-hydro-thermal units to overcome frequency deviations. Design/methodology/approach...

...Igor Korotyeyev Purpose The purpose of this paper is to introduce a method for the analysis of steady-state processes in periodically time varying circuits. The method is based on a new definition of frequency responses for periodic time-varying circuits. Design/methodology/approach Processes...

... Continued fraction Frequency response Orthogonal polynomials Recent progress in semiconductor devices increases the switching frequency for power control. This causes a very small skin depth for the eddy-current (EC) field compared with the conductor size in electric machinery. An efficient...

..., reduced order approach is used in the control system design. This study applies the modal decomposition method and the modal truncation method, thus retaining the lower order bending modes. The obtained numerical results are compared with the measured open loop frequency responses and the existing...

... Equation 8 Frequency response Modelling Design Multivariate analysis Parametric models of interconnect or packaging systems are of paramount importance for signal integrity analysis and real‐time design exploration and system optimisation. The decrease in IC feature size and the ever...

... systems are often not known. For their identification, a method based on the frequency response calculation utilizing the Welch method is now presented. The main focus of the work is directed to the measurement of the frequency response by exciting the system with pseudo‐random binary signals...

... the winding line terminals. In the next section, the deviation of the admittance resonance frequencies (from those of the base case) will be investigated. © Emerald Group Publishing Limited 2007 Transformers Winding Deformation Modelling Laplace transforms Frequency response...

... applied to tabulated responses data coming either from measurements or full electromagnetic simulations. In principle, the identification of measured frequency responses can give rise to greater difficulties, due to the presence of measurement noise. However, the performances of existing algorithms show...
