Research For Running Real-time Simulation And Control System Of Railway Vehicle Based On DSP

While the growing needs for motor control performance, ordinary Single Chip Micyoco doesn't meet the request more and more. Because ordinary Single Chip Micyoco handles the ability is not very strong, it can't meet the Real-time simulation of railway vehicle. It's the development of DSP technology that provides strong assistance to the implement of advanced control theory and complex control algorithm. In the TMS320C24x series of DSPs of Texas Instruments, TMS320LF2407A has the most complete and strongest character, it's replacing TMS320F240 and TMS320LF2407, and becoming the most rivalrous digital motor controller.Therefor an experimental platform of motor control is designed based on TMS320LF2407A in this paper. On the platform through the model of traction calculation is processing to Real-time simulation and running control.This system provides the abilities of educational experiment and product exploitation, permits on-line debugging. According to traction characteristic curve and braking characteristic curve with the system, setting up the pre-arranged circuit, weave a circumstance and carry a rate and traction and braking handle begin with system a RS232 for, passing the machine of PC a realizes with DSP customer plank correspondence Meanwhile the whole system of hardware and software adopts modularized design, abundant ports exist, and the usage is very convenient and flexible. Utilizing this experimental platform can achieve the research of different control algorithms and different control targets in the least time. The Real-time control to the speed and torque of the motor group is implemented. The experimentation indicates that this system can work reliably and achieve the prospective goal. It implemented the task of the...
