Computational speed-up of numerical differentiation of resolver signals
Dmitry V. Samokhvalov, Fedor Statsenko · 2015
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 differentiation calculation time estimation for a microcontroller is given.
