控制信号

The system is partly a multivariable control system which means that one output action variable (e.g. chemical charge) is controlled from more than one source (e.g. two feed forward signals, one feedback signal and an operator bias input).

该系统是部分的多变量控制系统，就是说一个输出动作变量是由多于一个的源变量(比如两个前馈信号，一个反馈信号和操作员的偏置输入)来控制的。

One is used to give out clock pulse to control the velocity, another is used to give out directional signal to control the direction.
