Abstract:
1. A torque control device for a power system, comprising: a target torque signal generation section which generates a target torque signal according to the power system's target torque; a plurality of actuators which operate in accordance with input command signals and cause the power system to achieve torque according to the operation; a plurality of signal processing filters which are mounted on a signal input section of each actuator and allow only a portion of supplied signal having frequencies at which the corresponding actuator is operative to pass through as a command signal for corresponding actuator; a signal distribution structure which distributes the target torque signal to the actuators according to a predetermined distribution priority order, the signal distribution structure supplying, for the highest-order actuator in the distribution priority order, the target torque signal to the corresponding signal processing filter and supplying, for the actuator of which the order is less than or equal to second-order in the distribution priority order, a signal obtained by subtracting a signal that has passed through the signal processing filter for the next high-order actuator from a signal that has not passed through to the corresponding signal processing filter; and a feedback structure which, if there is a difference between a signal that has not passed through the signal processing filter for the lowest-order actuator and a signal that has passed through, ensures that a difference signal representing the difference is reflected in the generation of a target torque signal by the target torque signal generation section.
