What does the inner loop of a Cascade controller do?(1)
a. The inner loop offers an early warning to the system controller.
b. The inner loop iterates to find the most optimal fit to the control response.
c. Disturbance in the inner loop convolutes the outer loop control.
d. Set point changes in the inner loop are fed to the outer loop
