Self-regulating systems with feedback loops, i.e., the routing back of the output of a system to its input, have existed since antiquity and have since become an integral part of modern technology.

控制系统通常根据有没有反馈会分为开环系统和闭环系统，在闭环系统的控制中，PID算法非常强大，其三个部分分别为； PID算法可以自动对控制系统进行准确且迅速的校正，因此被广泛地应用于工业控制系统。 2 开环控制 首先来看开环控制系统，如下图所示 ...

Plant engineers and technicians are frequently asked to tune the controller when a control loop’s process value has prolonged or significant excursions from the set point. But in many instances, no ...

The two most common categories of process responses in industrial manufacturing processes are self-regulating and integrating. A self-regulating process response to a step input change is ...

[Matt] wanted to have more control over his meat smoker so he built this advanced PID smoker controller. It uses the solid state relay seen in the bottom-right of this image to switch the smoker’s ...
