A system to emulate railway DC systems is presented in this paper. The emulator is designed to simulate the behavior of railway systems in terms of stray currents and touch voltages. Power electronics circuits are used as variable resistors to simulate the train motion. The emulator provides a test-bed to not only study and analyze the effects of stray currents and touch voltages, but to also evaluate...
This paper presents a general technique for modeling fluid, or gas, dynamic systems specifically for the development of control systems. Essentially the numerical methods which are generally used in computational fluid dynamics are borrowed to create either continuous-time or discrete-time models of the particular fluid system. The resulting equations can be either left in a nonlinear form, or be...
