The cross-coupling compensation controller is a device for multi-shaker vibration testing to avoid deviations from the test specification caused by the inter-actuator forces. The applied theory and the developed closed-loop control algorithm are first introduced. An embedded real-time controller with PCI interface is designed to implement the algorithm. A bussimulating based system architecture design method is proposed for simplifying the logic design. To satisfy the special requirements of the forward channels, a multiple mode data acquisition subsystem is also designed. The system uses the embedded real-time kernel uC/OS-II as the algorithm development platform. The whole vibration control process is divided into several tasks, of which the communicating mechanism is given, according to their importance. The results of simulations and experiments demonstrate the feasibility of the proposed method.
