| Outline of Final Research Achievements |
This paper considers dead-time compensation and attitude control of pneumatic anti-vibration apparatuses. First, we propose the tuning method of model of apparatuses and setting method of time delay in a Smith predictor. Then, in order to avoid the rotation of the apparatuses due to dead time, we present the attitude control method, which employs reference shaping. The effectiveness of this method is demonstrated by experiment. Finally, we consider the bandwidth expansion of pressure control system of anti-vibration apparatuses under the condition that the dead time exists. It is shown that resonance and anti-resonance can be suppressed by using Smith prediction and relative displacement derivative positive feedback, resulting in the expansion of control bandwidth.
