摘要: 本文采用了一种新的适用于实时在线控制的递阶算法，并在分布式计算机控制系统上予以实现．应用这种算法，可减少两级之间通讯的信息量，使控制级任务减轻，协调级的计算简单，收敛速度快，局部任务的选择自由度大．本文所设计的分布式计算机控制系统具有通讯可靠，易于扩充、维护等优点．实验证明，用该系统实现实时动态大系统的递阶控制有较理想的结果．Abstract: A new decomposition—coordination algorithm,which is very efficient for on-line hierarchical control of large scale dynamic system,is implemented on a distributed computer control system.In this implementation the amount of information exchange between the coordinator and the local agents is reduced.The computation in each local agent is also simplified.The convergence of the coordination strategy is very fast and the flexibility of allocating the computation tasks among local agents in the lower level is greatly increased.Through using local area network,the connection among microcomputers is more efficient and reliable.The advantages of the system are generality,extensibility and maintainability.Carefully designed experiments show that distributed computer control systems is a desirable implementation of the hierarchical control for large scale dynamic systems.
