Multivariable Predictive Control

4 days IR/MPC
Level
Advanced
Audience
  • Engineers, technicians and operation supervisors involved in the design, implementation and maintenance of Advanced Predictive Control (APC) projects.
Purpose
  • This course provides advanced & practical knowledge of multivariable predictive control.
Learning Objectives
  • Upon completion of the course, participants will be able to:
  • learn the fundamentals of multivariable predictive control: setting time, step response, prediction, dynamic control and optimization,
  • use a software for dynamic model identification, controller design, off-line closed loop simulation, robust tuning,
  • enhance skills required to specify, execute and maintain an APC application.
Prerequisite
  • Basic knowledge in instrumentation & process control.
Ways and means
  • Developed with the assistance of AXENS - IFP Group Technologies. About 30% of the course is devoted to workshops using AXENS software tools.
