Liner Quadratic Optimal Control in Active Control of Structural Vibration Systems

摘要：

The linear quadratic optimal control is employed to design the controller for a system of active control of structural vibration. In order to achieve the global optimal, a new method to optimize weighting matrix based on genetic algorithm is proposed, which can deal with the difficulty of choosing weighting matrix. Finally, an example of three-degree-of-freedom structural system is provided. The simulation results demonstrate the effective of this method through researching its dynamic response under EICentro seismic waves.
