Abstract (en)
[origin: WO2016016685A1] A drive for a home appliance (100) comprising (a) an electric motor (150) connectable to an operating tool of said home appliance (100); (b) a power regulating element (130) energizing said motor (150); (c) a Hall sensor (140) generating an electric signal corresponding to rotating speed of said motor (150); and (d) a PID controlled (120) preprogrammed to receive electric signals from said Hall sensor (140) and generating a PID output applicable to said regulating element (130) such that a predetermined rotating speed is maintained constant. The PID output is computed according to the following equation: Formula (I), where e k is a present sample, e k-1 is a previous sample, e k-2 is a last previous sample; X is in a range between 1.5 and 2, Y between 1 and 3, Z between 1 and 3.
