Title:
ACTUATOR DRIVING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2012/090343
Kind Code:
A1
Abstract:
An actuator driving apparatus is provided with: a digital filter (10) for conducting phase compensation of a torque command digital signal, using a fed back digital signal; a digital PWM generating unit (11) for generating a plurality of pulse-width modulated PWM control signals in accordance with the output of the digital filter; an H-bridge unit (12) for switching between first and second terminal voltages and outputting the switched voltage, in accordance with the plurality of PWM control signals; first and second continuous-time ΔΣ A-D converters (13) for conducting A-D conversion of the first and second terminal voltages, respectively; and a feed back filter (14) for implementing decimation processing to the output of the first and second continuous-time ΔΣ A-D converters (13), and feeding back a digital signal to the digital filter.
