Abstract:
In the test, the control system gives command signal to make the engine and test process systems complete a predetermined test task according to certain procedures. In order to adapt to the high-accuracy control requirement of a new attitude and orbital control engine, it is necessary to improve the existing control system. Therefore, a new control system was designed based on field programmable gate array and high-speed solid-state relay. Its control module can be used for operators to control various electromagnetic valves in the test system manually and automatically. Its record module can be used to record the status of the system, so that the command staff know the working status of the system. The system can meet the testing requirements of the new attitude and orbital control engine. The control precision is 0.1 ms.
