When the output intensity of a laser is changed, a feedback control signal processed by a digital PID regulator is used to control the current of a laser tube.

利用输出光强变化，通过数字PID调节器反馈控制激光管电流可获得较为稳定的激光输出。

Combining the nonlinear control system theory and the aim of chaos synchronization, we designed a nonlinear feedback controller for synchronizing the scalar output signal of Chua's Circuits system.

把非线性系统的微分几何理论与混沌系统的同步控制目标相结合，设计了蔡氏电路混沌系统的标量混沌信号同步控制的非线性反馈控制器。

It works by a control mechanism called negative feedback, and the thermostat is measuring the temperature and then sending a signal to a heater somewhere.

是通过一种叫做负反馈的控制机制，探测器测量温度，再把信号传给加热器。
