Permanent magnet synchronous motor low inverter power consumption direct torque control method and device

The invention relates to a permanent magnet synchronous motor low inverter power consumption direct torque control method and device. The permanent magnet synchronous motor low inverter power consumption direct torque control method adopts predictive control strategies. Compared with the space-vector-modulation-based direct torque control and the common direct torque control, the permanent magnet synchronous motor low inverter power consumption direct torque control method has the advantages of enabling the integral inverter switching frequency to be the lowest, optimally using a power device and reducing the switching loss of the inverter due to the facts that predicted values of the torque and the stator flux linkage are predicated according to an interior model of a controller based on the given reference values of the torque and the stator flux linkage and a most suitable switching position for the inverter is obtained through a minimization objective function which comprises the flux linkage, the torque and the average switching frequency within the forecast time domain and enabling online computing time to be greatly reduced due to the fact that the control law is fed back through an offline computing state, maintaining good dynamic performance and robustness of the common direct torque control and maintaining the flux and the torque to be within a corresponding hysteresis range.

Traffic signal optimization control method for vehicle queuing overflow state at road intersections

The invention relates to a traffic signal optimization control method for the vehicle queuing overflow state at road intersections, and overcomes the defect that an image monitoring and control signal lamp cannot apply to queuing overflow optimization control compared with the prior art. The method of the invention comprises the following steps: traffic flow parameters of a road intersection are acquired; the queuing length is calculated; the queuing overflow state at the road intersection is judged; and the green light time of an upstream intersection is calculated. The queuing length parameters and queuing overflow events are detected in real time by vehicle detectors installed at the entrances and the exits of road intersections, and balancing of the queuing lengths of all intersections in a region is realized by adjusting the green light time of traffic signal control, thus solving the problem of queuing overflow at intersections.
