Design Control System of Telescope Force Actuators Based on Linuz

摘要：

By analyzing the characteristics of large telescope and the function structure of telescope actuator control system, distributed Ethernet force actuators control system is applied. To improve the performance of stability and real-time, developed software of force actuators control system in realtime Linux, a hiberarchy schedule scheme based on RTAI is presented. Adopt QT designer to design the user interface of control system in master computer. Master computer and controllers intercommunicate asynchronously no-block via QServerSocket, QSocket and DSocket, design communicate frame format. In order to communicate among processes, SLOT and SIGNAL are adopted. Finally depicted the main algorithm of data received in main controller.
