Abstract

The challenge of handling process parameters such as flow, level, temperature,
and pressure, which is regarded as the most significant problem in the process industry
environment. In a spherical tank, the cross section area of the tank varies nonlinearly as
the height of the tank changes, so shape of the level changes in a nonlinear manner. The
nonlinear system is used by most of the process industries for storage purposes, like cement,
sugar, paper & pulp, oil, and gas. The maintaining and controlling the process parameter
liquid level of the spherical tank is critical for system stability, and the controller is
designed for simplicity and improved performance. In this research work the control
algorithms in the enhanced PID controller were selected. The Enhanced PID employs a
velocity form of algorithms, and the resources on which the loop operates a change in errors
to change the output. They are in charge of the system's stability as well as the proportional,
integral, and derivative control values are then determined using the PIDE auto-
tuning method. This is very effective for adaptive gains as well as multi-loop and cascade
control. Conventional PID control systems used in controllers have positional form
and work directly on errors not suitable for large systems. So, the Logix5571 controller is
used to control spherical tank that communicates IO’s remotely via Ethernet IP and Modbus
master-slave connection.
