Direct Digital Control (DDC) Systems
Direct Digital Control (DDC) is the automated control of a condition or process by a digital device. DDC takes a
PID Controllers : Parallel, Ideal & Series
For better or worse, there are no fewer than three different forms of PID equations implemented in modern PID controllers:
PID Controllers Graphical Analysis
A common exercise for students learning the function of PID controllers is to practice graphing a controller’s output with given
PID Controller Response with different Input Signals
A very helpful method for understanding the operation of proportional, integral, and derivative control terms is to analyze their respective
Overview of PID Control terms
PID control can be a confusing concept to understand. Here, a brief summary of each term within PID (P. I,
Derivative (Rate) Control Theory
The final element of PID control is the “D” term, which stands for derivative. This is a calculus concept like
Integral (Reset) Control Theory
Imagine a liquid-level control system for a vessel, where the position of a level-sensing float sets the position of a
Proportional-only Offset
A fundamental limitation of proportional control has to do with its response to changes in setpoint and changes in process
Proportional-only Control Theory
Imagine a liquid-level control system for a vessel, where the position of a level-sensing float directly sets the stem position
