The governor is a device which is used to controlling the speed of an engine based on the load requirements. Basic governors sense speed and sometimes load of a prime mover and adjust the energy source to maintain the desired level. So it’s simply mentioned as a device giving automatic control (either pressure or temperature) or limitation of speed. The governors are control mechanisms and they work on the principle of feedback control. Their basic function is to control the speed within limits when load on the prime mover changes. They have no control over the change in speed (flywheel determines change in speed i.e. speed control) within the cycle. Take an example: Assume a driver running a car in hill station, at that time engine load increases, and automatically vehicle speed decreases. Now the actual speed is less than desired speed. So driver increases the fuel to achieve the desired speed. So here, the driver is a governor for this system. So governor is a sys...
