What is the effect of increasing the P term in a PID controller?
Increased response times and more overshoot and oscillation
What is the primary function of the integral term in a PID controller?
To correct long-term drift or bias in the system
What happens if only a Ki gain value is set in a PID controller?
Instability will always increase

To adjust the system response based on how far away it is from the desired value
What is the effect of a large P term on the system response?
It leads to more oscillation and instability
What happens to the derivative term output when the error changes faster?
It increases to dampen the system's response
What is the primary role of the derivative term in the system?
To stabilize the system and improve its transient response
What happens when the Kd gain value is too high?
Sudden changes in the system cause overshoot
