This paper makes use of PID control, Fuzzy- PID control based on single parameter these two control strategies to simulate the systems model. Compared with common vehicle, the results of simulation show that the vehicle equipped with the electromagnetic power steering system has better yaw velocity frequency response characteristic under condition with step input of steering wheel, so it has more betterhandling stability; Compared with PID control strategy, the results show that the Fuzzy-PID control strategy has the advantages, such as response fast, stabilize itself quickly and less over-altitude.

本文使用了PID、单参数自整定Fuzzy-PID两种控制策略对系统模型进行控制，仿真结果表明：相对于普通汽车，装有电磁式助力转向系统的汽车在方向盘转角阶跃输入的情况下，汽车横摆角速度频率响应特性更好，因此具有更好的操纵稳定性；而相对于采用PID控制，采用单参数自整定Fuzzy-PID控制又可以使系统响应更迅速、超调量更小、稳定更快。

Other exterior enhancements include new Roof-Mounted Off-Road Lights built into the roof rack air dam as a standard feature for Off-Road models, along with new side-step and roof rail colors and a new 4x4 badge on Xterra 4-wheel drive models.

其他外观的改进包括新的车顶上安装的越野灯到车顶行李架，作为关闭的标准特征路模式，以及新的侧步和车顶的颜色和铁路新的4x4徽章上的Xterra 4轮驱动气坝建模型。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
