A study for the control algorithm of vibration simulation system using multiple shakers and sensors is presented. The classical multi-shaker control theory and methods are first reviewed, from which the simulation results are given. A modified self-tuning algorithm with controllable convergence behavior is proposed to get better control near the modal frequency of the structure. Some judgment rules are developed to prevent the user from specifying a impossible spectra matrix. To verify the algorithm, a real-time control system using the real-time kernel VxWorks as the algorithm development platform is designed. A series of highly efficient vector and matrix algorithms which is the core of the random vibration control process are achieved. The results of simulations and experiments demonstrate the feasibility of the proposed method.
