XPC-based real time control system for an electro-hydraulic servo shaking table

Shaking table is widely used in aerospace, automobile and architecture for research in the fields of Civil, Mechanical and Electrical Engineering. Three variable controller is applied for an electro-hydraulic servo shaking table which has eight sets of hydraulic system and is under acceleration control. To achieve real-time control performance for the shaking table system, XPC-based control system which is operated by host-target type is developed. The host computer is used to send commands and monitor the system, while the target computer equipped with data acquisition boards is used for real-time computation. The logic controller in the target computer is used to system and error diagnosis. The two computer are connected by Ethernet. The proposed control system is easy to program, adjust parameters and has good real-time performance.
