    摘要： Disclosed herein are methods of generating an active crank series of signals that is derived from at least two series of signals, wherein one or both of the series of signals have been modulated to produce two series of signals that resemble each other. Also disclosed herein is a crankshaft positioning system for determining the rotational position of a crankshaft of an engine that utilizes at least two crank angle sensors 10 and 12. The signal information from the two crank angle sensors 10 and 12 is processed by a signal processor 150 such that the series of signals 220 from the second crank angle sensor 12 emulates the series of signals 210 from the first crank angle processor 10. The signal processor generates an active crank series of signals 230 based on the two series of signals 210, 220. The active crank series of signals 230 is sent to an engine control processor 120 which directs the injection and/or ignition of fuel into cylinders of an engine. According to the system exemplified herein, the active crank series of signals 230 sent to the engine control processor 120 is not disrupted despite failure of one of the crank angle sensors. These and other embodiments are disclosed.

    摘要： A diagnostic technique for monitoring shaft cracking or incipient pinion slip involves monitoring a shift in a characteristic natural frequency of an operating system such as a geared system of a locomotive. The technique involves monitoring a shift in the characteristic natural frequency or resonance of a shaft for detecting shaft cracking. The technique also involves monitoring a shift in the characteristic natural frequency of one or more assemblies of the operating system which include a pinion and detecting a shift in the one or more characteristic natural frequencies of the assemblies. A vibration sensor or measurement of current changes of a motor of the operating system can be used to detect vibrations to monitor the characteristic natural frequencies. Torsional oscillations or measurement of current and voltage changes of a motor of the operating system, can also be used to monitor the characteristic natural frequencies.

    摘要： The present invention provides a apparatus and method for controlling the force and velocity of a piston within the clamp assembly of a injection molding machine. The control unit comprises the following elements: a PI based cascade compensator; an estimator coupled to the clamp assembly and the cascade compensator, wherein the estimator is utilized to estimate the position of the clamp assembly piston; a velocity position controller coupled to the clamp assembly and the estimator, wherein the velocity position controller is adapted to generate a velocity error signal based on the piston velocity signal; and an auto selector coupled to the cascade compensator, wherein the auto selector is adapted to select between the velocity error signal and the force error signal to generate a valve command signal. The present invention additionally employs a method for determining the velocity profile of the piston of a clamp assembly. The method comprises the following steps: determining the maximum displacement xs of the servo valve; selecting a final velocity vs of the piston; choosing a ratio &agr; of the piston ramp-down interval to the servo valve displacement “x” during a ramp-up interval, selecting a desired maximum piston velocity (vmax) during the ramp-up interval and a constant speed interval; and determining servo valve displacement xu from simulations or estimate from previous cycles.

    摘要： An adhesion control system for a locomotive is provided for achieving and maintaining a maximum adhesion value. The adhesion control system includes a means for determining from an appropriate adhesion-creep curve an ideal creep rate that must be achieved and maintained in order to achieve and maintain a maximum adhesion value, a means for estimating an actual creep rate through the measurement or estimation of motor or wheel acceleration and locomotive acceleration, a means for selecting a creep rate set point based on a comparison of the actual creep rate and the ideal creep rate where the creep rate set point is set to a positive value if the actual creep rate is less than the ideal creep rate minus an acceptable differential and is set to a negative value if the actual creep rate is greater than the ideal creep rate plus the acceptable differential, and a means responsive to the creep rate set point for adjusting the operation of the locomotive so that the maximum adhesion value may be realized where the actual creep rate is increased if the creep rate set point is set to the positive value and is decreased if the creep rate set point is set to the negative value.
