Fluxgate sensors have the second harmonic voltage amplitude with the magnetic field strength is proportional to the adoption of second harmonic filter through phase-sensitive detector rectifier, to achieve full-wave rectifier, low-pass filter in through the phase-sensitive detector after the second harmonic into a smooth DC signal, on the one hand to the back of the circuit, on the one hand, the magnetic flux through the door to feedback regulation, the opposite magnetic field generated with the measured magnetic field, so that the work has always been zero fluxgate magnetic field, thus ensuring the most high-precision fluxgate.

磁通门传感器产生的二次谐波电压幅值与磁场强度成正比，二次谐波通过通过滤波器再通过相敏检波器整流，实现全波整流，在通过低通滤波器将相敏检波后的二次谐波转化成平滑的直流信号，一方面送到后面的电路进行，一方面通过反馈调节送到磁通门中，产生与被测磁场相反的磁场，使磁通门始终工作零磁场下，从而保证磁通门的最高精度。关键词：磁通门磁力仪，相敏检波器，磁场

The Nash equilibrium problem with l2-nor m bound disturbance was studied. The problem was considered as a compound dynam ic game described by N-person non-cooperative dynamic game and two-person zer o-sum dynamic game. By applying H∞ control theory method, the existence conditions of linear quadratic Nash equilibrium H∞ disturbance attenuati on strategies were presented and proved, and its state feedback Nash equilibrium solutions were given.

D models are the most widely spread in the world of turbo-machinery for its simplicity, but they are indeed purely empirical correlations which not only fail to provide detailed information inside one or more components, but also require significant effort to recreate themselves if engine operating conditions or component representations change; quasi 3-D models have been the workhorses for compressor and turbine design for many years, and the primary benefit of using quasi 3-D system models is to facilitate the design and detail analysis of a particular component across the range of possible boundary conditions; Full 3-D models are gradually replacing quasi 3-D ones by virtue of requiring no exit flow angle model and loss model and being capable of predicting secondary flow in cascade.

零维模型由于使用时简单易行，因此在涡轮发动机的仿真中得到广泛应用，但零维模型作为纯粹的经验关系式无法反映部件内部的流动细节，并且一旦部件有少许改动则新特性的建立耗费巨大；准三维模型由于能够详细地提供部件内部的流动情况，方便设计而成为涡轮和压气机设计的主要工具；全三维数学模型正逐步取代准三维模型在涡轮设计中的主导作用，同后者相比前者能够预测叶轮机械内的二次流动，在粘性流计算时不需要气流角和损失的经验公式，因此拥有巨大的发展前景。

For the auto mentioned in the paper, we analyze and establish the dynamic equations under different power systems, respectively discuss the system efficiency of HEV under the conditions of whether the storage battery power is zero or not, utilize the SQP to compute the corresponding optimal decelerating rate and optimal storage battery power under the conditions of different speeds, different demand torsions and different storage battery SOC; then use the optimal computation results to summarize the rules of auto optimal control, provide the foundations for the optimal control rules in the future.

对于本车，分析并建立了在不同动力系统工作模式下的动力学方程；分别讨论了当蓄电池功率为零和蓄电池功率不为零两种情况下的HEV的系统效率；利用序列二次规划法来求解出在不同车速、不同汽车需求转矩和不同蓄电池SOC情况下对应的最佳减速比和最佳蓄电池功率；利用优化计算结果，初步总结了一些车辆优化控制规则，为将来更好的优化控制规则提供了依据。
