Description
Technical field
The invention belongs to system integration technology field, more particularly to one kind are used for networked system integrated optimization control side
Method.
Background technology
The Optimal Control Problem of complication system is one of focus of Recent study work, and traditional Dynamic Large-Scale Systems pass rank
Controlling is all to obtain on the premise of accurate model, however the mathematical model of many real systems to be only actual certain near
Seemingly, accurate model is difficult to obtain, thus being difficult to obtain the optimum control of real system.
Complication system often has the features such as regionality and the internetworking of distribution.Networked system refers to the complexity of networking
System, i.e. complication system under network environment, it is characterized in that by computer network, each subsystem being connected constitutes a networking
Complex large system, network environment can be LAN or btemet network.With the development of computer network and its technology,
Network communications technology is greatly improved, and the scale of network is also greatly improved so that originally disperseing more difficult reality
Existing data output and exchange, can realize, the transmission of its information all relies on network and enters in the network environment of " insertion "
OK.Optimization problem in real system is ubiquitous, simultaneously because the development of computer network and its technology so that scattered,
The complication system with provincial characteristicss defines the networked system with distinct characteristic.
Content of the invention
It is an object of the invention to provide a kind of be used for networked system integrated optimization control method, by using non-linear
Dynamic Large-Scale Systems hierarchical control method and dynamic integrated system optimization and parameter estimation, solve existing networked system
Integrated optimization control accurate model is difficult to obtain, thus being difficult to obtain the optimal control problem of real system.
For solving above-mentioned technical problem, the present invention is achieved by the following technical solutions:
The present invention is that one kind is used for networked system integrated optimization control method, comprises the steps:
Each subsystem is connected by network environment and constitutes the complication system of a networking by ss1；
Ss2 adopts Nonlinear Dynamic big system hierarchical control method and dynamic integrated system optimization and parameter estimation phase
It is optimized in conjunction with to this complication system；
Ss3 carries out integrated optimization control to networked system, obtains the optimization solution of complication system under network environment.
Preferably, described ss1 appoplexy involving the collateral environment is LAN or btemet network.
Preferably, the big system hierarchical control method of described Nonlinear Dynamic and dynamic integrated system optimization and parameter estimation side
Method is first, to carry out spatial decomposition to big system, the optimization problem of whole system is decomposed into the optimization of each subsystem, and leads to
Cross upper strata coordinator and coordinate the optimization solution to obtain whole Dynamic Large-Scale Systems, and the optimization of each subsystem is system optimization
With the integrated λ of parameter estimation so pass through the system coordination of outer ring iterative and inner ring system optimization and parameter estimation integrated
The true optimal solution when there is differences between model and reality for the actual Nonlinear Discrete Dynamic Large Scale System can be obtained eventually.
The method have the advantages that
1st, the networked system integrated optimization control of the present invention adopts Nonlinear Dynamic big system hierarchical control method and moves
State system optimization and parameter estimation integrated approach, except providing optimized algorithm, are analyzed it is ensured that optimization method to its performance
Implement, the performance of the integrated optimization control method of networked system includes real-time, optimality, convergence and its robustness.
2nd, inventive network systematic integration optimization control real-time before the network that induces one, for trans-regional complexity
System, implements integrated optimization control by means of computer networking technology, can preferably solve trans-regional complication system integrated
The real time problems of optimal control.
Certainly, the arbitrary product implementing the present invention it is not absolutely required to reach all the above advantage simultaneously.
