Abstract

Several control algorithms for architectural structure considering and ignoring influence of structure-soil interaction (SSI) are discussed respectively. Corresponding to stochastic analysis, the H₂ norm is regarded as optimal index. To definite analysis, the H_infin norm is regarded as an optimal index. They have their own advantages and defects. The mixed H₂/H_infin control scheme gives a scheme that minimizes H₂ norm of the closed-loop system on condition that the H_infin norm is smaller than a definite value (gamma). The systems controlled by three types of controllers which based on two types of model (considering and ignoring SSI) respectively are studied. A simulative example is given
