Abstract:
A control system equalizes the torques of a lead and a slave engine driving a common load by comparing the throttle settings of the engines and controlling the slave engine throttle with a speed signal equal to the algebraic sum of the lead engine speed signal and a control adjustment signal equal to the sum of an adjusted, selected gain times the sum of the instantaneous error signal and the integral of the error signal over an adjusted, selected reset time.
