This course is for engineers and technicians  responsible for maintaining process control performance using instrumentation and control loop tuning

Overview

MLT is a 3-day course that introduces participants to effective methods for determining optimal tuning parameters for regulation of processes. The non-oscillatory EnTech tuning techniques, based on Lambda concepts, are taught with a focus on minimizing process variability. Effectiveness is gained by the implementation of a tuning strategy that matches control element dynamics to process operating requirements. It contains formal lectures that are amply populated with process examples and supported with hands-on lab exercises using PC-based process simulators. Participants learn how to recognize acceptable/ unacceptable control loop performance and to identify the most common source of problems. Fundamental tuning concepts, including the PID controller, process dynamics, valve motion characteristics (backlash and stiction), setpoint tracking and regulation, minimum variance, integrating processes, and level control are studied.  High fidelity process simulators are used as the basis for the labs and simulation analysis.

Prerequisites

Some experience with process instrumentation and control is helpful.

Topics

• Process Dynamics –perform bump tests to identify process model (gain, deadtime, time constant and valve dynamics) to determine PID tuning.
• Self Regulating loops – apply Lambda tuning to first-order and second-order process loops (flow, pressure, temperature, pH, etc)
• Integrating loops – tune levels and header pressures for load recovery and setpoint response
• Process Interactions – Lambda tune loops to minimize interactions and increase production
