The Research Of Helicopter Blade Dynamic Balance Experimental Platform Control System Design And Realization

The main research object in this dissertation is helicopter blade dynamic balance experimental platform system. The background of this dissertation, helicopter blade running elevation measurement system and the software of control system are discussed in this dissertation.In the first, the background of this dissertation, the he status which helicopter blade dynamic balance experimental platform system design and using are introduced, helicopter blade dynamic balance experimental platform system is not designed in our country, so in this Dissertation, the advanced experience is accepted and some innovative methods also are used in the system design.The helicopter blade running elevation measurement is the kernel part of helicopter blade dynamic balance experimental platform system, also is the main part of this dissertation. The method of blade running elevation measurement is discussed and analyzed at first, then the measurement erroneous is analyzed, the construct design also is discussed at last.In the control system design part, the every of subsystem is introduced. The refresh time of PLC, the communication style between PLC and upper programmer are also discussed.The software design is discussed in this dissertation finally. The three subsystems of the whole system software are discussed in detail.
