Abstract
Abstract A clutch control system and clutch assembly utilizing same includes a comparator (10) for receiving a signal (A) corresponding to actual engine speed from a sensor member (6) and a signal (D) corresponding to desired engine speed from a sensor member (8) to provide an output signal (A-D). Signal (A-D) is provided to a summer (16) as well as a differentiator (14) which operates upon (A-D) to provide the differential with respect to time ##EQU1## which is received by summer (16) which provides the function signal ##EQU2## to an actuator (2) which utilizes the functional signal to control clutch (4). The functional signal may also include one or more weighting factors such as (K 1 ) to control the magnitude of signals (A) and/or (D) and/or (A-d) and/or ##EQU3## in the manner desired.
