From the view of torque controlling strategy, the relation between the torque controlling strategy such as the electric current feedback method、 PWM open loop method etc and the vehicle driving way is analyzed firstly, then the conclusion could be drawn that the PWM open loop method has more advantages than the electric current feedback method when they are both used in the same vehicle which is direct driving by hubcap motor. Secondly, based on the electric motor mathematic model and its experiment, a new permanent brushless dc motor phase electric current detector method in which a digital signal processor and single current sensor are used is introduced.

从转矩控制策略角度来看，分析了电流反馈法以及开环PWM电压调速控制方法与车辆的驱动方式关系，得出了电机驱动电压受限的情况下，无论是从对车辆的动力性能影响还是从对车辆的驱动要求来讲，开环PWM电压调速控制方法较电流反馈法更适用于以轮毂电机直接驱动方式的两轮电动车中；其次，根据电机的数学模型以及电机试验波形，提出了一种利用数字信号处理器以及单个电流传感器检测三相永磁无刷电机电枢电流的新方法，这种方法具有较强的适应性、实时性，它可以根据控制系统的要求，适时地提供所需电流数据，是目前许多文章关于无刷电机相电流平波的重要技术基础。

Feedback Mode presents a balance, reciprocal and harmony scene in intergeneration. Inter-generational relations contains the ultimate value of family continuity to the Chinese people, the ethical norms of filial piety, supra economic feedback action in Inter-generation. On the basis of it, it constructs the three-in-one model which is consisted of the value, ethic and action.

费孝通先生关于中国社会代际关系的"反馈模式"理论给我们呈现的是一种代际间均衡、互惠、和谐的景象，代际关系内含了中国人对家庭延续的终极价值追求、孝道的伦理规范和超经济的代际反馈行动，它们支撑起了家庭养老模式的运行。

When the amplifier output is in either the positive or negative saturated state, the positive feedback network provides a voltage at the non-inverting input which is determined by the attenuation of the feedback loop and the saturation voltage of the amplifier.

不论放大器输出是正是负，只要OP达到输出饱和状态，OP正反馈路径就会在OP同相输入端加上一个电压，该电压的大小由OP正反馈路径的衰减和OP输出饱和时的电压共同决定。

This paper researches on the normal form and synchronization of strict-feedback and general strict-feedback chaos systems.

本论文主要对严格反馈和广义反馈混沌系统的标准型和同步控制进行研究。

One hundred and eleven students took part in the experiment. The results showed that multi-stage feedback of other members was the most important cue of dynamic decision-making and it was the base of cooperation. The environment uncertainty and value orientation of members will also interact with feedback and have effect on cooperation.
