Servo mechanism technique based anti-reset windup PI controller for pressure process station

Background/Objectives: In this paper a new architecture is followed which is based on manipulating feedback structure for pressure process. Methods/Statistical Analysis: This work copes with the research based on anti-reset windup mechanism. Mathematical Modeling of pressure station is carried out using two-point method. Windup action is being complication in FOPDT process, thereforedesigning a controller for such problem is always a big challenge for control engineers. As a part of controller design direct synthesis method has been used. Apart from controller design, architecture of system will also influence the system performance. Tending towards architectural manipulationa new structure has been followed. Findings: Result shows the significance and positive approach towards the proposed model for pressure processin both simulation and real time. Controller action can be optimized in a reliable way and energy utilization of actuator gradually reduced. Applications/Improvements: In some real time nonlinear processes windup action manipulates plant process more than required limit, where process leads to saturation. In such scenarios the proposed approach provides plant to regain its position and act within limits of its boundary.
