dc.description.abstract | The design of a practical torque sensing governor which can be used with any type of prime mover and load was accomplished. An investigation was performed to determine the advantages of such a governor as applied to a small internal combustion engine. The characteristics of the engine, torque sensor, and load were determined in order that the system composed of the aforementioned elements could be simulated on an analog computer. The simulated system was governed by a simulated torque sensing governor and optimized, then the same procedure was followed with a simulated proportional-integral-derivative governor. The real system was then governed by each type of governor using the optimum values of governor parameters obtained from the simulated system. The control response curves of the real and simulated systems using both governors were obtained by application of a step-change in load. From these response curves it was determined that for both the real and simulated systems the torque sensing governor produced less speed error for less time than the proportional-integral-derivative governor. Open-loop frequency response data were taken for the real system using each governor and the Nyquist stability criteria applied. The Nyquist criteria showed the system to be stable when either governor was used. The Nyquist plots showed that the torque sensor reduced phase lag more than the derivative component of conventional control. | en |
