Development of PLC Based Level Control System for Conical Tank System for Water Treatment Plant

The controller's primary responsibility in the process industry is eliminating numerous disruptions and maintaining stability. Like any process tank, the shape is crucial in the design of regulators. To lessen land and water pollution, wastewater treatment facilities are becoming increasingly common in many industrial and organizational sectors. Conical tanks are crucial components of sewage treatment facilities. In wastewater applications where the tank must be empty, cone bottom tanks are utilized to stop sludge from the tank from getting into the subsequent operations. Conical tanks are used in the process sector because it is simple to empty their contents. Controlling the level of liquid is an essential responsibility in many operations. In this research, the liquid level is managed in a conical tank system without interactions. Level control is incredibly challenging for conical tanks because of their non-linear features and wide range of size and diameter. Current methodologies incorporate Proportional-Integral-Derivative (PID) controllers in their control systems. 90% of automated controllers used in the process sector are PID controllers, the foundation for many sophisticated control algorithms and techniques. PID controllers are the industry standard for feedback control, and are commonly used in linear systems because of their simplicity, versatility, and effectiveness. However, the presence of non-linearities in the process can limit their applicability. This study describes the maintaining process levels at specified operating conditions and achieving optimal performance using a fuzzy-tuned PID controller.
