Assume implementation of PID control in the system. Increasing each of the parameter of the controller will result in:
We can't say anything about it without knowing the system model exactly.
P - Eliminates steady state error, I - Changes nothing, D - Increases overshooting
P - Increases settling time, I - Increases steady state error, D - Increases overshooting.
P - Decreases settling time, I - Eliminates steady state error, D - Decreases overshooting.
