It is a common situation in electronics to have a control loop, that is some sort of feedback that drives the input to a system such as a motor or a heater based upon a sensor to measure something ...

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 ...

PID loops are a central component of modulating boiler control systems with applications ranging from basic steam header pressure control to cascading 3-element drum level control. A modern ...
