A study for the real-time control algorithm of random vibration testing system using multiple shakers and sensors is presented. The classical multi-shaker random vibration testing control theories are first reviewed, from which the simulation results are given. A modified self-tuning algorithm with adaptive convergence behavior is proposed to get better performance near the modal frequency of the device under test. A real-time control system using VxWorks as the algorithm development platform is designed to verify the algorithm. A series of highly efficient vector and matrix algorithms which is the core of the random vibration control process are achieved.
