What is PID Control?

PID Controller Definition

A PID controller is a crucial device in control systems that adjusts the control action based on proportional, integral, and derivative terms of the error.

Control Parameters

Proportional (Kp), integral (Ki), and derivative (Kd) components each uniquely influence the response and stability of control systems.

Proportional Control

This mode adjusts the output proportionally to the error, which is the difference between desired and actual performance.

Integral and Derivative Actions

Integral control focuses on the accumulation of past errors, whereas derivative control predicts future errors, helping to refine the control process.

Applications and Limitations

PID controllers are versatile and widely used in modern industrial applications, though they face challenges in noisy environments and optimal control scenarios.
