Abstract
A continuously variable transmission and method for preventing transmission belt slippage in the case of a sudden increase in load torque on the transmission involves both inserting a lag in the transmission to allow the control loops time to respond to the sudden increase in load torque and speeding up the responses of the control loops in response to the sudden increase in load torque. The transmission is used to drive an aircraft electrical generator at a constant speed in the disclosed embodiment.
