Abstract:
-For many applications, Proportional-Integral-Derivative (PID) controllers are the optimum choice and will simply outperform almost any other control option. This is why they are currently used in over 95% of closed-loop processes worldwide. PID is a feedback mechanism that calculates the error value between the measured process variable and the desired set-point [1]. It is composed of three control parameters – Kp, Ki, and Kd – which regulate the output by determining the error, minimizing the error and stabilizing the output. [3] This paper describes one application of the PID controller and implementing it using 0.35?m CMOS technology. The PID controller design aims to manipulate the output of a type of a step-down dc-to-dc converter to a target value using Ziegler-Nichol’s first tuning method.
