Abstract
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.
