PID controller

A PID controller is a technology used to manage systems and processes, like temperature or speed. It stands for Proportional, Integral, and Derivative, which are three methods of adjusting the control based on current errors and past performance. The proportional part addresses the current error, the integral part considers the accumulated past errors, and the derivative part predicts future errors. Together, they help maintain a desired output by continuously adjusting inputs to minimize error, ensuring systems operate smoothly and efficiently. This is widely used in industries to enhance automation and precision in various applications.
