摘要： A control for machine members propelled at plural points along their length to move linearly transverse to member length determines and eliminates skew of the driven points. Skew is determined from position indicated by position transducers associated with the driven points. Various types of position transducers are accommodated, including encoders having outputs from which member position can be determined only with reference to marker outputs of the transducer. For such encoders, the control effects velocity controlled motion to detect position. Skew is eliminated by relatively moving the driven points by the magnitude of the skew.

摘要： A method and apparatus for limiting current through a switching device supplying current to a load. A control evaluates a model representing the switching device temperature as a nonlinear function of current and time. The model compares the temperature of the switching device to a maximum allowable temperature. The current limit is defaulted to peak current; and in response to the model detecting a temperature in excess of the maximum allowable temperature, a nominal current limit is set. The current limit reset to peak current after the model detects a switching device temperature a predetermined magnitude below the maximum allowable temperature.
