LQG PREDICTED CONTROL BASED ON RBF NEURAL NETWORK
In order to solve the effect of time lag in the process of structural vibration control,Linear Quadratic Guassian Predicted Controller (LQGPC) is deduced based on RBFNN.This controller can forcaste the control force at next serveral steps according to to-be moment response of controlled structure.Then the signal of control force at next serveral steps was set to control system accroding to time lag of control system.Finally,A five-story smart isolated frame structure is analyzed by adopting the LQGPC in the case of different time lag.Simulation results show that control effects of LQG and LQGPC have the favorable control efficiency and both two algorithms can decrease the response of the structure effectively in the case of no time lag,but LQGPC still has better ability of controlling structural response in the case of different time lag existing in system.
