Design of High Quality Controller to be Advantage over PI with Low-Pass Controllers

In this paper, an advanced PI control method was analyzed. The analysis of Bode plot in frequency domain, and the experiment shows that advanced controller is better than the existing PI controllers. They can achieve higher bandwidth, lower settling time and better disturbance rejection ability. The increased performance costs little in sensor noise amplification. We show using true-life design examples that advanced control algorithms improve equally well both speed and position controllers
