New system and motion equations of the semi_active variable stiffness·damping control system are suggested. On the basis of predictive control, predictive instantaneous optimal control algorithm is put forward. The comparative shaking table tests of the subject models with and without the AVS·D device were carried out. Results of tests show that the AVS·D system is very effective and confirm that both the control algorithm and software of the AVS·D system are efficacious.
