If the drive is designed based on the requirements for efficiency, it is necessary to check out effectiveness of control methods and design solutions at the modeling stage. For this purpose numerical model should provide measurements of the instantaneous values of efficiency. This paper offers method which allows calculations of the instantaneous efficiency of permanent magnet synchronous machine...
Modeling of numerical differentiation of position sensor signals is carried out. Formulas with variable number of terms of series are compared. Accuracy ranking for each equation is done.
The article is devoted to creation of clarified mathematical model of stepper motor in Simulink. The main advantage of this model is opportunity for further development to taking into account the steps missing and torque drops which could not be accounted for the hybrid stepper motor library block.
Currently in use numerical differentiation of position sensor signals method consisting in derivative calculations by logarithmic differentiation is considered. The new speeded up derivative calculation method compared with the previous one is brought forward. Generalized mathematical operations quantity-counting formulas for either method with variable number of series terms are obtained. The numerical...
