Design of the Measuring and Controlling system for Missile Actuator Based on LabWindows/CVI

It is about a measurement and control system based on virtual instrument development platform of LabWindows/CVI, thus establishing a universal missile steering gear performance test platform for performance test both in idle-loading and loading of various steering gears including electric actuator and pneumatic actuator, which are used in missile as vital actuator of control system. In this paper,the composition of hardware structure and the software flow of the testing and controlling system for missile actuator are introduced. The dynamic link library, database, multi thread technology and so on are used in the process of software designing. By application of these techniques, performance test for steering gears could be completed accurately and rapidly. The result of application showed that this measurement and control system has features of stable working, high testing precision, strong commonality, fully automation, easy extended, meeting the requirements of steering engine test accuracy and technical specifications, thus providing a good test environment for performance research and design improvement of steering engine.
