The amount of feedback in an open loop system affects the pe

The amount of feedback in an open loop system affects the performance of the system. The magnitude of the force on each bearing, as a result of a gyroscopic couple on a rotor, depends on the distance of the bearing from the centre of mass of the rotor. The type of input signal to a system does not have any effect on the response of the system as long as the initial conditions remain unchanged.
