RESEARCH ON DIGITAL FILTERING ALGORITHM USED IN MEASUREMENT SYSTEM OF BALANCING MACHINES

Design of filter removing interference is a key technology in measurement system of balancing machines. Transfer functions of five digital filters——synchronous time average, Chebyshev narrow band-pass filter, integral digital filter, digital tracking filter and adaptive filter are given, their applications in measurement system of balancing machines were investigated in detail. From the point of view of practicability, their filtering abilities and realization methods were analyzed and compared. As a result, some instructive conclusions are provided for selection of digital filter of balancing machines.
