primary feedback

This is not reasonable. In fact, one-class SVM is, in analogy, an open-loop system. The criteria setting have to initiate from the primary problem for one-class SVM since there is no feedback information.

文中指出，单类支持向量机的模型选择问题，可类比于一个开环系统，由于缺乏反馈信息，所以模型选择的切入点只能从优化主问题入手。

In the feedback control loop the liquid slag temperature at outlet of flow deflector is measured which used as primary controlled variable and the current in electrode is measured which used as secondary controlled variable.

在这个控制方案中，导流槽出口液渣温度须进行测量，并作为主被控变量，导流槽中电极的电流也须进行测量，并作为副被控变量。

If usability is a primary concern of your system then you should organize teams so that they are close to end users so as to ensure they can easily obtain feedback from the end users.

如果您的系统主要关注可用性，那么您应该组织团队，使他们靠近最终用户，以便他们可以很容易地获得最终用户的反馈。

The designed control circuit consists of two components: isolating and sampling circuit used for sampling output voltage and isolating primary and secondary of the converter; type 2 error amplifier, designing compensated circuit for error amplifier to stabilize feedback circuit system.

设计的控制电路由两部分组成：隔离、取样电路，用来采样输出电压并实现变换器初、次级电气隔离；2型误差放大器，设计补偿电路使反馈电路系统稳定。
