基于此，本文提出了一种采用PI算法调整模糊控制器比例因子的模糊控制器，该控制器

In view of disadvantages in present defect reconstruction methods,such as over-long time or excessive need for training samples,a new defect reconstruction method based on similar model and genetic algorithm was investigated as follows:similar model between non-axisymetric defect and axisymetric defect was represented,and proportionality factor was deduced by skin depth equation.

针对以往缺陷重构方法中普遍存在的计算时间长或需要大量训练样本的缺点，提出一种基于相似模型和遗传算法的缺陷快速重构方法，分析非轴对称缺陷与轴对称缺陷之间存在的相似模型，并利用集肤深度公式推导出两者之间的缩比因子，从而将耗时巨大的缺陷重构问题转换为二维轴对称情况下的计算问题；同时为进一步缩短重构时间，提出一种加快遗传算法收敛速度的方法。

To the condition of deviation from side path when vehicles are turning and braking, according to the deviation distance, the control strategies and control algorithms of vehicle braking stability by two control methods, yaw moment and active steering, are determined. The fuzzy controller are designed whose outputs can be adjusted online according to the variation of slip rate and dynamic proportionality factor. The simulation results prove that the method of fuzzy control which is based on the yaw meoment and front wheel active steering can improve vehicle braking stability and ability of path tracking.

针对汽车在转弯制动时出现的侧向路径偏离状况，根据偏离量大小，利用横摆力矩和主动转向两种控制模式分别进行汽车制动稳定性控制，确立了两种控制模式下的控制策略和控制算法，设计了模糊控制器，根据轮胎最优滑移率变化状况，对模糊输出变量论域的大小按照动态比例系数进行实时在线调整，仿真实验验证了所提出的基于横摆力矩和前轮主动转向的模糊控制方法能提高汽车制动稳定性和路径跟踪能力。

The principle of proportionality may effectively limit the implementing of national public power and coordinate public interest and private interest by weighing benefits. The principle has broken the absolute concept of the private interest's superiority or the public interest's superiority and put the two interests into the concrete situation for analyzing.

比例原则可以有效地限制国家公权力的行使，最大限度地保护公民私权利，并且通过利益衡量的方法，在公共利益与私人利益之间进行协调，打破了私人利益至上和公共利益至上的绝对观，从而使二者处于具体情境中待分析的状态，没有哪个处于绝对优先的地位。

"Second Life is remarkably easy to work with, and is very popular,"

"第二次生命是显着容易的工作，并且很受欢迎，"

For example, we usually assume that materials are homogeneous and isotropic and free of internal defects or flaws.
