The invention relates to an optimal control system for subway traffic flow. According to the system, a topological structure diagram of a rail transit network is generated according to planned operating parameters of trains; controllability and sensitivity of train flow are analyzed on the basis of the topological structure diagram; a multi-train conflict-free operating track is generated according to the planned operating parameters of each train; at each sampling moment, the advancing position of each train in the future time is predicted according to the current operating state and the historical position observation sequence of the train, an observer from continuous dynamics to discrete conflict logics of the train is established, and the continuous dynamics are mapped into conflict states expressed by discrete observation values; when the system possibly breaks the traffic control rule, hybrid dynamic behaviors of a subway traffic hybrid system are monitored, and alarm messages are provided for a control center; finally, when the alarm messages appear, the train operating track is subjected to robust bi-level programming with a self-adaptive control theoretical method, and a program result is transmitted to each train.

The invention relates to a navigation control method based on rolling planning strategies. The method includes the following steps: obtaining real-time and historical position information of ships through sea surface radar; at each sampling time, carrying out rolling prediction of trajectories of the ships within a future period of time according to the real-time and historical position information of the ships; observing sequences on the basis of current running states and historical positions of the ships, and obtaining a value of a sea wind field variable; on the basis of the running states of the ships and a safety rule set the requirement of which a set ship needs to meet when the set ship is running within the sea, monitoring dynamic behaviors of the ships and providing timely warning information to a sea traffic control center; and when the warning information appears, adopting an adaptive control theoretical method to conduct rolling planning for ship collision-prevention trajectories by setting an optimization index function and merging the wind field variable value under a condition that the ship physical performance and sea traffic rules are satisfied, and transmitting a planning result to the ships for implementation.

The invention belongs to the field of radio communication, and discloses a channel self-adaptive estimation method based on multi-model weighted soft handover. Firstly, the channel system model is established, the time-frequency dual channel is selected, and the channel parameters are determined. Then based on the channel model and estimation method, the channel estimation sub-model and multi-model channel estimation library are established, and the model error and estimation error of the channel estimation model are analyzed and calculated. Finally, according to the switching index combining model error and estimation error, the model switching is completed through the weighted multi-model adaptive estimation algorithm of LUMV. The present invention proposes that under the condition of uncertain transmission channel model, combined with channel model and estimation method, the multi-model idea in multi-model adaptive control theory is introduced into channel estimation, and a weighted multi-model with minimum variance of linear error is adopted An adaptive estimation method is used to complete the switching, so that the channel estimation method has high robustness and accuracy in the complex channel range.
