基于混合逻辑动态模型的电力牵引传动系统硬件在环仿真
Hardware-in-the-loop Simulation for Electric Traction Drive Systems Based on Mixed Logical Dynamic Model
摘要
Abstract
For accurate modeling of an electric traction drive system considering the traction converter's all possible switching states and smaller simulation step size, a hardware-in-the-loop (HIL) simulation approach based on mixed logical dynamic (MLD) model was proposed and implemented on a field programmable gate array (FPGA). The MLD models of the interlaced single-phase PWM (pulse-width modulation) rectifiers and the three-phase PWM inverter in the electric traction drive system were built based on the switching functions, which are the logical expressions under the current and voltage conditions. The simulation step size was limited in 500ns by assigning appropriately the computation sequence of the discretized modules. The results of the HIL simulation compared with Simulink simulation demonstrate the validity of the proposed HIL simulation method. Compared to modeling on a general processor, modeling on a FPGA with MLD model further reduces the simulation step size and reacts fast to the switching signals.关键词
