초록

The dynamic instabilities in a system which controls prime mover output torque and angular velocity separately are avoided by deriving an accelerating torque signal in an output torque controller where it is added to a sensed torque signal, and the added signal is compared to a commanded torque signal, the difference signal value therebetween serving to control the output torque.

대표
청구항

Apparatus for providing a signal for controlling the output torque of a prime mover driving a load in a system having rotating parts of known rotational inertia including an output shaft controlled at a commanded torque value, the output shaft controlled at a commanded angular velocity by controlling the load absorbing capacity of the load, the system having signals associated therewith having magnitudes indicative of the actual angular velocity, a commanded torque value and an actual sensed torque value, comprising: means responsive to changes in the ac...
