Abstract: In this paper, a hybrid robust active vibration controller is proposed for reducing single-degree-of-freedom (SDOF) and multiple-degrees-of-freedom (MDOF) isolation platforms vibration. The controller combines adaptive feedforward with filtered-x least mean squares (FXLMS) algorithm and robust controller using H/sub inf/ synthesis theory for obtaining the desired robust performance and fast convergence. The control plant configurations are identified by a frequency-domain technique and implemented by using a floating-point digital signal processor (DSP). Experiments are carried out to evaluate and compare the performance of feedforward control, feedback control and proposed hybrid controller for reducing the vibration at two test isolation platforms. The results of experiment indicate that the proposed hybrid technique is effective in reducing the vibration and yield the best performance for the test isolation platform systems. The comparisons of three control structures also are described in this paper.
