| Abstract: | For seismic response control for the system with distributed parameters, the motion control equation of the system with distributed parameters is presented and sequential optimal modal control algorithm is derived. Due to the full state requirement of sequential optimal modal control algorithm, the full state observer is proposed. Then the full state of the system under earthquake is reconstructed by the seismic response of the system easily measured by feedback sensors. Therefore, the seismic response control for system with distributed parameters is realized in the actually engineering by using the sequential optimal modal control algorithm based on full state observers. A seismic response control case of the isolated 330 KV voltage transformer is analyzed by adopting sequential optimal modal control algorithm and sequential optimal modal control algorithm based on full state observers respectively, suggesting that the two control algorithms have the favorable control efficiency for the system with distributed parameters under earthquake and the displacement of isolation layer and acceleration of upper voltage transformer are decreased in different degree. In addition, the sequential optimal modal control algorithm based on full state observers can control the seismic response of the system with distributed parameters by the feedback seismic response measured easily and has the same control effect with sequential optimal modal control algorithm adopting full state feedback. |
| Keywords: | system with distributed parameters seismic response vibration control full state observers modal control algorithm |
