Review of the filter structures was made. Digital filters allow filtering the speed signal in control loop of direct drive with a mechanical resonance. The analogue filter equations were transformed into digital filters to enable tune them in real time. Digital filters and tuning algorithms have been implemented for signal processor SHARC family. Implementation of digital filters was done using C language and complex data structures in C++ language. The presented algorithms and transformation enable to reduce time needed to implement the digital filter in the speed control loop of the analysed drive system.
