Ziegler-Nichols Closed-Loop Method (Ultimate Gain)
Closed-loop refers to the operation of a control system with the controlling device in “automatic” mode, where the flow of
Control Systems
We have the largest collection of Industrial Control Systems articles like industrial automation, Distributed Control Systems (DCS).
Heuristic PID Tuning Method
Heuristic PID Tuning Method In contrast to quantitative tuning procedures where definite numerical values for P, I, and D controller
Quantitative PID tuning procedures
A quantitative PID tuning procedure is a step-by-step approach leading directly to a set of numerical values to be used
What we need to Know before Tune a PID Controller ?
We know the benefits of robust PID control Tuning. Increased productivity, decreased equipment strain, and increased process safety are some
Steady-State Process Gain
When we speak of a controller’s gain, we refer to the aggressiveness of its proportional control action: the ratio of
Runaway Processes
A classic “textbook” example of a runaway process is an inverted pendulum: a vertical stick balanced on its end by
Integrating Processes – Liquid Level Control
A good example of an integrating process is liquid level control, where either the flow rate of liquid into or
Self-regulating Processes – Liquid Flow Control
If a liquid flow-control valve is opened in a step-change fashion, flow through the pipe tends to self-stabilize at a
Process Dynamics and PID Controller Tuning
To tune a feedback control system means to adjust parameters in the controller to achieve robust control over the process.
PID Controller Functions
For any PID controller to be practical, it must be able to do more than just implement the PID equation.
