The application of modern control theory in the field of engineering structure vibration is not strong mainly because it has a little considerations of actual constraint, the paper conducted a study on this issue.According to structural dynamics theory, a state-space model contains input time-varying delay, actuator failure, parameter nonlinear, etc.is established.The model parameters were appropriately dealt with to lower the conservatism.A robust H∞ reliable active control algorithm for multi-constraints was also proposed based on both state feedback and LMI approaches.Finally, a building model with four degrees of freedom subjected to the EI Centro earthquake is simulated and studied utilizing the algorithm, and the results show that the proposed method is feasible and thus can be used to control the vibration of engineering structures.
