What is PID, how is works

Question

Accepted Answer

PID stands for Proportional-Integral-Derivative. It is a control algorithm used in systems to maintain a desired output.

PID is a feedback control mechanism that continuously calculates an error value based on the difference between a desired setpoint and the actual output of a system.
The Proportional term adjusts the output proportionally to the error value.
The Integral term sums up the error over time to eliminate steady-state errors.
The Derivative term predicts future errors based on the rate of change of the error.
By adjusting the weights of these terms, the PID controller can optimize the system's response.
For example, a PID controller can be used to regulate the temperature of a room by adjusting the heating or cooling output based on the difference between the desired temperature and the current temperature.
