Implementation of Logarithmic Number Systems in control application using FPGA
Ivan Klimo, Michal Kocúr, Peter Drahoš · IFAC-PapersOnLine · 2019
This paper deals with a different approach to hardware implementation of PI controller. Logarithmic Number Systems (LNS) are used for number representation instead of classic, floating point (FLP) or fixed point (FP) representation. The comparison and pros and cons of these representation are presented. The results shows, that using LNS can be another way to implement controllers. The implementation were realized on Field Programmable Gate arrays (FPGA).
