Analysis Of PID Controller For Second Order System Using NI Labview

چکیده
Many processes and systems work well only within a narrow range of physical parameters like temperature, humidity, pressure etc. Certain chemical reactions, biological processes, and even electronic circuits perform best within limited parameters ranges. So, these processes need to be optimized with well designed controllers that keep physical parameters to within specified limits or constant. PID algorithm based controller is the most popular within the process industries. It is a robust easily understood algorithm that can provide excellent control performance despite the varied dynamic characteristics of process plant. This paper presents the implementation and comparison of different controller strategies like P, PD, and PID in NI LabVIEW software. Keywords— LabVIEW, PID, Process Model, Steadystate error, Overshoot, Rise time, Settling time, Gain margin, Phase margin, Step Response Test, Ziegler– Nichols’ tuning methods.

LabVIEW implementation of an enhanced nonlinear PID controller based on harmony search for one-stage servomechanism system
This paper presents a practical implementation for a new formula of nonlinear PID (NPID) control. The purpose of the controller is to accurately trace a preselected position reference of one stage servomechanism system. The possibility of developing a transfer function model for experimental setup is elusive because of the lack of system data. So, the identified model has been developed via gat...
