The Research on H2 Optimal Control Applied to Active Vibration Isolation
In considering transmissibility of force and the output force of actuator, the transfer function was got between input excitations and out performance. Adopting different feedback control variable as velocity, force, full state etc, the H2 optimal control was applied to double layer isolation system. By analyzing the amplitude-frequency characteristics of transfer function, comparing the advantages and disadvantages of various feedback control strategy, the best control method of H2 is determined.
