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.

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： Closed loop control apparatus and methods for reducing ripples in an extruded plastic sheet include, for example, a closed loop speed control system having a roll speed sensor, a roll speed controller, and a roll drive. The roll speed sensor is communicatively coupled to the active extruder roll and configured to determine an actual roll speed of the active extruder roll. The roll speed controller is communicatively coupled to the roll speed sensor and utilizes the actual roll speed and desired roll speed to generate a command signal and transmit such signal to the roll drive. The roll drive is communicatively coupled between the roll speed controller and the active extruder roll, and utilizes the command signal to drive the active extruder roll, through its controllers and power electronics.

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.
