英文摘要：

The characters of Linear Quadratic Gaussian （LQG） control algorithm were introduced and the active Sequential Optimal Control （SOC） algorithm was proposed based on the fuU states feedback. Compared with LQG control algorithm, the gain matrix in SOC control algorithm had the feature of time variation. A five-story base isolated building frame structure was used to evaluate the control effect in the case of sensor normal working and sensor contaminated with noise by Simlink simulation, Simulation results show that overall control effect of SOC is advantageous over that of LQG and SOC has good robustness.
