Multi-target cooperative intelligent controller for track traffic and method adopted by same

Abstract

The invention relates to a multi-target cooperative intelligent controller for track traffic. The multi-target cooperative intelligent controller mainly comprises a planning module, a selection module, a cooperative module and a plurality of independent sub control channels, wherein the independent sub control channels comprise a self-adaptive module, a PID (Proportion Integration Differentiation) controller, a driver, a controlled motor and a photoelectric encoder. The controller adopts the following control method that the operation position, speed and acceleration of track traffic are planned by the planning module; the selection module can be used for selecting a proper main control signal according to the current object; the cooperative module can be used for adjusting and distributing a work signal of each independent sub control channel; each operation motor for track traffic operates according to the signal in the independent sub control signal; and finally, information is fedback to each independent sub control channel, the cooperative module, the selection module and the planning module by each independent sub control channel, and thereby a multi-target control task is finished. According to the multi-target cooperative intelligent controller disclosed by the invention, the operation process of the track traffic can be started and braked smoothly; and the multi-target cooperative intelligent controller has stable operation speed and accurate parking position.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a multi-objective cooperative intelligent controller and method for rail transit. Background technique [0002] With the rapid development of the economy, the urban population density is constantly increasing, and the level of modernization is also constantly improving. Rail transit has been recognized as the most convenient, efficient, safe and environmentally friendly public transportation, and has become a new bright spot for improving people's lives. At present, in China, rail transit has the characteristics of short distance between stations, high traffic density, large passenger flow, and relatively crowded during peak hours. It is very important to ensure driving safety and improve operating capacity. For this reason, newly-added rail transit in China (such as Shanghai Rail Transit Line 7 to 12) has gradually installed screen door systems in the waiting area, wh...
