Question:

Figure P11.34 illustrates an active vibration control scheme for a two-mass system. An electro hydraulic actuator between the two masses provides a force that acts on both and is under feedback control. The system model is
m1 1 = k1(y - x1) - k2 (x1 - x2) - c(1 - 2) - f
m2 2 = k2(x1 - x2) + c(1 - 2) + f
