17. Overshoot, Rise Time, Settling Time

Tuning a system depends on the situation and the characteristics of the system. The video provides you with some guidelines on how to approach the tuning process.

A good practice is to start with the requirements that you need for your system, such as speed, accuracy, stability, etc.

Precisely how you want the system to behave over time (therefore focusing on T-rise and overshoot) and the frequencies (bandwidth and damping ratio).

For example, if you want to reduce T-rise, you can increase the value of the P-gain (Kp).
On the other hand, increasing the D-gain (Kd) decreases overshoot and improves the stability.

Here below a reference of how different Kp, Kd values can affect the time domain of the system.
