Genetic Algorithm Based on Active Control Structure
2) The provisions of control range when the} the better control effect, that the control effect is proportional to the input energy. When the scope of control over a large, imposing no restriction on the size of control, the structure of the reaction can be controlled to almost zero as shown in Figure (2 - 1). for different structure and different loads, to control the structure of a reaction is zero, the need to control the size of the range is different. Figure (2-3), (2-4) were plotted in the control range l when the structure of the control response (solid line) comparison chart. Figure (2-3) in the solid line is to consider a time lag of 0.12s when the method calculated by the control exerted on the structure, the structure of the time history graph, and the ideal situation with no time delay calculated control applied to the structure, the structure of the time history (Figure (2-2) as shown in solid lines) compared to control effect can be seen almost the same, after controlling for the ideal case of the maximum displacement of 3.78cm There, after delay to control the maximum displacement of the structure of 4.36cm. Figure (24) is to consider the results when the delay is 0.16s, and Figure (2-2) control the effect is almost the same compared to the control of the maximum displacement after 4.38era. Figure (2-3), (2-4) is shown in the dotted line the time when there is delay,[link widoczny dla zalogowanych], but did not consider the ideal case delay calculated in accordance with the structure imposed on the control, the structure of the control response, you can see,[link widoczny dla zalogowanych], not only failed to control the structural response of the purpose of control imposed upon the contrary, the structural response of the structure than when no control reaction (dashed line shown in Figure 2-2) also intense, which fully shows that,[link widoczny dla zalogowanych], in practical applications If you do not solve the delay problem probably is not the purpose of control of structural response and to make matters worse, this delay can be seen in problem solving is the key to realization of online control structure. 4 Conclusion of comparative analysis of the above examples can be seen. The proposed structure of genetic algorithm method and the theory of online control solution to the problem of delay is correct, feasible and effective. The control system has significant practical value. References 1ChungLL, WangYP, TungCC. Instantaneouscontro [ofstructureswithtime-delayconsideration.
