ABSTRACT:
A throttle controller comprising circuit means for accomplishing numerous improvements including means to convert the reactive load cell torque value into a true torque value instantaneously using an extremely simple passive circuit; together with means to use this value together with either load or power feedback values to generate a true shaft load signal. The circuit also includes improved means to permit the throttle controller to provide a single pulse usable for the dual functions of driving either a servo or a solenoid type actuator, in addition to other types of actuators for the throttle of the engine being tested.
