A PID (Proportional Integral Derivative) controller is a common instrument used in industrial control applications. A PID controller can be used for regulation of speed, temperature, flow, pressure and other process variables. Field mounted PID controllers can be placed close to the sensor or the control regulation device and be monitored centrally using a SCADA system.
The industrial PID has many options, tools, and parameters for dealing with the wide spectrum of difficulties and opportunities in manufacturing plants. Some of the options such as “dynamic reset limit” have existed for decades but the full value and applicability has not been realized. Also, the possibilities extend considerably beyond the original intent into improving process efficiency, operability, and compliance for sustainable manufacturing. An enhanced PID developed for wireless measurements has been found to inherently eliminate oscillations from a wide variety of sources including discontinuous and delayed responses in the automation system and interactions between loops when used with a threshold sensitivity setting and the dynamic reset limit. The advancements in new techniques and a greater understanding of existing capabilities enable the PID to not only improve loop performance but to individually optimize unit operations.
The PID controller is an essential part of every control loop in the process industry
Studies have shown that the PID provides an optimal solution of the regulator problem (rejection of disturbances) and with simple enhancements, provides an optimum servo response (setpoint response)
Tests show that the PID performs better than Model Predictive Control (MPC) for unmeasured disturbances in terms of peak error, integrated error, or robustness
The PID controller in the modern Distributed Control System (DCS) has an extensive set of features. However, primarily due to the lack of understanding of the functionality.
