Research For Railway Vehicle Simulate To Circulate Controller Based On DSP

My passage is about the design and development of the Railway Vehicle Simulate to Circulate Controller that is appropriate for any power grade and any velocity grade on the requirement of the development of the electric traction of railway vehicle and the control system of the electric braking. The controller is designed based on DSP as the core controller in this paper. The chip of DSP is a kind of special microprocessor and controller. This system makes use of high speed processing characteristic of TDSLF2407EA to design the device of orbit vehicle that simulates to circulate motor control and the corresponding experiment platform. The device can be used for different grade power traction system and can be carried on the dynamic state simulation, according to simulation can get a railroad train under the condition of pre-arranged circuit, carry a rate, traction characteristic, braking characteristic, weave a circumstance information of speed variety regulation.The controller makes use of 550V/15kw power grade motor group to do the experiment about dynamic state simulation of the railroad train. One is company motor controlled by speed mode and the other is tested motor controlled by torque .In the traction condition, the company motor controlled by traction inverter is used by generator to simulate the railroad train circulate, and the tested motor is used by electric motor ; In the braking condition, the tested motor controlled by traction inverter is used by electric motor to simulate braking dint, and the company motor simulate braking characteristic. According to communicate between the RS232 of PC with DSP can attach the early value to the railroad train(include trailer weight, motive car weight, controlling car weight, traction characteristic, braking characteristic, carry a rate, weave a circumstance information etc),combine software simulate railroad train resistance model(include slope resistance, curve resistance, air resistance),Utilizing the theories of railroad train exercise can really complete dynamic state simulation of the railroad train, the Real-time control to the speed and torque of the motor group is implemented. The design of the system can be used in the control system of electric traction of railway vehicle and electric braking. Pass the software constitution, this device and can be make use of in the railroad train that the different power grade leads the system imitates to circulate the experiment, replacing to pack the car experiment. For the experiment terrace that the electric power leads the product development to provide a" the half is whole true", can rise to shorten to experiment the period, reduce the purpose of cost.
