    Abstract: The present method can determine the inertia of an electric motor and the load driven by the electric motor in situations where the electric motor accelerates or decelerates in a non-linear manner. During acceleration and deceleration, the torque produced by the electric motor is sampled periodically and the average values for the acceleration torque and deceleration are calculated. The rates of acceleration and deceleration also are determined. These values are employed to derive a value indicating the inertia.

    Abstract: An improved electronic line shaft provides for a predictor sending predicted position and/or velocity values to servant drives that may be later strobed in by high speed low-latency strobe signals to eliminate network jitter and delay. The predictor may be implemented as a phase lock loop, providing filtering of a master encoder signal together with flexible electronic gear ratio adjustments and other desired control refinements.

    Abstract: A method for determining motor velocity includes generating an edge signal including a plurality of edges. The edge signal indicates rotational travel of a motor. Edge counts in the edge signal occurring during periodic sample intervals are determined. The edge counts are filtered over a predetermined number of samples. A velocity feedback signal is generated for the motor based on the filtered edge counts. A drive unit for controlling a motor includes an edge detection unit, a position accumulator, and a velocity filter. The edge detection unit is operable to receive a motor position signal and generate an edge signal including a plurality of edges. The edge signal indicates rotational travel of the motor. A position accumulator is operable to determine edge counts in the edge signal occurring during periodic sample intervals. The velocity filter is operable to filter the edge counts over a predetermined number of samples generate a velocity feedback signal for the motor based on the filtered edge counts.

    Abstract: In a real-time system of a digital control system, in order to prevent a single program sequence (PS2) of a non-time-critical computing process ("task") from using up a load-dependently disproportionate amount of the total computing time still available, the program sequence (PS2) is classified as a subordinate computing process (R14) that has a running-time limit (LZF). Sequences of program steps that are preferably not to be interrupted are in this case protected from interruption by a lock, the original running-time limit (LZG) being able to be run over only within predetermined limits.

    Abstract: A method and apparatus for control of one or more torque-regulated motors in a controlled system in which a feedforward velocity component is subtracted from an output of proportional-integral velocity regulator to soften the command response of the motor control, independent of torque disturbances reflected in the velocity feedback path. The velocity feedforward path is decoupled from the velocity feedback path. In a preferred embodiment, a digital-type motor controller is used to practice the method in controlling a paper processing line.
