A torque loop decoupler decouples a torque loop from a speed loop to allow only the speed loop to react to small, rapid changes in engine speed. The torque loop decoupler calculates a compensation signal and adds the compensation signal to a control signal of the torque control loop. The compensation signal keeps the control signal constant during small, rapid changes in engine speed. The compensation signal is calculated as the partial derivative of turbine torque with respect to changes in engine speed multiplied by a signal indicative of small, rapid ...
For an aircraft power management system having a speed loop which controls engine speed and a torque loop which controls engine torque, apparatus comprising: delta speed means for providing a delta speed signal indicative of small, rapid changes in said engine speed; compensating means, responsive to said delta speed signal, for generating a compensation signal that varies as a function of said small, rapid changes in said engine speed; and modifying means, responsive to said compensation signal, for operating on said torque loop such that said torque lo...
