An analytical method of simultaneous equations with constraint conditions by BOTT-DUFFIN inverse matrix is applied to active vibration control analysis of building structures for earthquake motions considering prescribed displacement modes. As the constraint condition in elastic response control, shapes of eigen modes are adopted. For the case of the first or second mode control only, the control characteristics about robust stability were already discussed anf'ytically by the author. In this paper, a new control force which is weighted sum of modal control forces is proposed. It was shown that effective control is made possible by using the new combined control forces. A new method of active vibration control analysis of building structures based on instantaneous optimal control and feedforward control is presented.
