- the PID control method is a control method that combines proportional control (P control), integral control (I control), and differential control (D control).
- P control is a control method that feeds back the difference from the target value by a constant gain. P control is controlled in a form that fluctuates by the deviation from the target value. If the control operation is performed by multiplying the gain using P control, the target value can be quickly approached. However, in cases where the target value cannot be properly tracked by P control alone, such as in systems of two or more orders, I control and/or D control methods can be added.
- I-control is a control method that integrates errors and feeds them back. In other words, I-control is a control method that accumulates errors and reflects them in the next cycle.
- P-control if a value that fluctuates greatly is performed under PI control, the overshoot is gradually reduced and the target value can be tracked.
- PI control if only PI control is performed, a value that fluctuates slightly arithmetically exists as a residual deviation, and the measured value can oscillate for a considerable period of time due to the residual deviation.
- D control is a control method that differentiates the error and feeds it back to the control system.
- D control is added to PI control, differentiation is applied in the form of a proportional and integrated graph, and by eliminating the residual deviation, the oscillating system can be controlled to follow the target value without error within an appropriate time.
