A PI (Proportional-Integral) controller is effective in eliminating steady-state offset, which is crucial for processes that must have no offset in the process variable. The integral component of a PI controller accumulates error over time and adjusts the control output to eliminate the offset, making it suitable for processes with small capacitance and slow but large disturbances.
