典型地，电动车辆中的牵引和电子稳定程序（ESP）以及传动系振荡阻尼应用在级联控制结构中实现，其中电流控制作为最内环。然而，电流控制动态通常由于控制器输出饱和和改变电机参数的非线性效应而变化。本文提出了一种电流控制方案，尽管这些非线性效应，确保了一个定义良好的动态行为。因此，叠加的控制回路的设计由于公知的线性动态而被简化，这又可以有益于整个控制回路的性能。
Typically traction and electronic stability programs (ESP) as well as drive train oscillation damping applications in electrical vehicles are realized in a cascaded control structure with the current control as innermost loop. The current control dynamic, however, is usually varying due to nonlinear effects as controller output saturation and changing motor parameters. In this paper a current control scheme is presented that ensures a well defined dynamic behavior despite these nonlinear effects. As a consequence, the design of superimposed control loops is simplified due to the well known linear dynamics, which in turn can be beneficial with respect to the performance of the entire control loop.
