... as an approximation function in the fitting (parameter adaptation) process using the Newton and Gauss–Newton methods. The structure of the adaptation system is presented along with the implementation in simulation environment. Findings It was confirmed in the simulation tests that Newton and Gauss–Newton methods...

...Xi Chen; Zhengwei Du; Ke Gong Purpose The purpose of this paper is to study the impact of high‐power microwave interferences on electronic devices needs the simulation of semiconductor components. Although the semiconductor equations can be solved numerically by Newton method, the conventional...

... nondifferentiability of the hysteresis operator. This is done by using differentiable substitutes or quasi‐Newton methods. Findings Numerical tests with synthetic data show that fixed point methods based on fitting after a full forward sweep (alternating iteration) and Newton type iterations using the hysteresis...

...Aurelio Medina; Antonio Ramos‐Paz; Claudio Rubén Fuerte‐Esquivel Purpose To introduce an efficient methodology for the computation of the periodic steady state solution of power systems with nonlinear and time‐varying components which combines a Newton method based on a numerical differentiation...
