Hierarchical Distributed Control System Design Software

Aiming at the design and implementation of the complex realtime control system,the thesis takes example for the intelligent manipulator, giving a structure of the hierarchical and distributed control system (HDCS) based on the realtime control system (RCS) module, advancing the analysis and design method based on the task decomposition for the complex control system, and raising to use the state transition diagrams to describe the work flow of every control task.Besides,the thesis illustrates how to realize the state transition diagrams by the state tables.The state tables convert the state transition diagrams into computer language,like C++ ,so as to complete the control task.To help the designer to design and implement the complex control system and enhance the development efficiency,the thesis designs to develop a design software for the HDCS and researches the design idea and implementation way of it.The design software takes an advantage of the GUI feature of Java programming language to develop the graphical design platform and diagnosis tool,making user build the structure of control system directly and flexibly, and use the software tool easily.On the other hand,the thesis studies to develop the design software library for the HDCS with C++ programming language,including RCS module and communication tool of control system.Moreover,based on the concept and properties of class and the merits of application programming interface (API) ,the thesis puts forwards to use the abstract class to realize the elements of the design software library,such as the control module(RCS module) class and the communication classes(Neutral Message Language and Communication Management System),encapsulating the bottom details of the application and providing the top interface for user,as leads to the interface between modules be simple and makes user master and use them conveniently.what's more,the control system developed by the design software has good expansibility and reusability.Futhermore,the thesis narrates the implementation way of the code generator.Finally,the thesis assumes to design the automated highway system by the hierarchical and distributed control method,and develop such complex system with the design software for the HDCS.
