SEQUENTIAL OPTIMAL PREDICTED CONTROL FOR SMART ISOLATED STRUCTURE

The characters of Radial Basis Function Neural Network (RBFNN) and Sequential Optimal Control (SOC) algorithm are introduced. For the effect of time lag in the process of structural vibration control, Sequential Optimal Predicted Control (SOPC) is presented based on RBFNN. This algorithm can decrease the influence of time lag effectively. A five-story base isolated frame structure is used to evaluate the control effect in the case of time lag and no time lag. Simulation results show that control effect of SOC and SOPC is equivalent and both two algorithms can decrease the response of the structure effectively in the case of no time lag, while SOPC can better control structural response in the case of time lag existing in the system.
