Definitions

  • engine-generator unit refers to the combination of
  • the first calculator is typically referred to as a "speed calculator” or “speed loop” and the second calculator is typically referred to as a "rack calculator” or a "power control loop”.
  • the overall result of the invention is a speed dominated system capable of producing optimum speed, fuel delivery and power settings at all times.
  • an electronic governor capable of providing improved objective operator response characteristics under changing load and changing power setting conditions. In general this is accomplished in a system of the type described above by providing an input to the power control loop or rack calculator which is a function of engine acceleration and which modifies or overrides the actual fuel delivery rate setting to prevent power dips or overruns which are characteristic of prior art systems.
  • a control system or electronic governor capable of flexibility in accommodating the performance characteristics of a given engine-generator unit is provided.
  • Figure 41 through 4L is a flowchart of a further option to Figure 4G;
  • Figure 5 is a block diagram of the invention as applied to the control of a diesel electric generator unit for a locomotive.
  • the memory 40 is preferably sub-divided into a random access portion 40a and an add-on ROM 40b which contains certain constants hereinafter defined which are unique to the particular engine 10 and generator 14 and which effectively tailor the governor 20 to the "personality" of the particular unit.
  • memory module 40b is hereinafter referred to as the "personality module”.
  • the conversion from a four-bit signal input (from the notched device 22) to a digital number is a straight-forward matter of look-up in a read only memory.
  • a signal proportional to desired power from a proportional version of the power setting device 22 can likewise be converted to a digital number in straight-forward matter to be used in the look-up table.
  • This output is applied to a ramp rate generator 60 which is part of the calculator 24 to smooth out transitions in desired speed numbers caused by a movement of the operator-controlled level in the device 22.
  • Ramp rate generator 60 causes the desired speed signal to undergo a transition between numbers having a plurality of stairstep type incremental increases or decreases, each increment being of fixed time.
  • Summer function 32 is correspondingly numbered in Figure 4B and, as is apparent, involves an arithmetic combination of two numbers.
  • the device 22 is provided with a fixed number of notch positions or power settings and does not, in itself, provide any proportional control between those settings in the locomotive case being described.
  • the look-up table functions the same.
  • measured engine speed obviously varies relatively smoothly between settings in a proportional or infinitely variable fashion and it is desirable to produce desired rack signals which are proportional to measured engine speed between the optimum operating points shown in Figure 2; i.e., the desired rack signal will follow straight line segments between the optimum operating points of Figure 2.
  • this proportional control calls for an interpolation function which is represented in the function blocks of flowchart 4E in the area of referenced numeral 44.
  • the transfer function of computer 54 is of the PID (proportional, integral, differential) type consistent with established control theory.
  • K 3' K 4 sized for application
  • NR speed valve used for determination of desired rack
