Application of closed-loop advanced control in industry has rapidly increased since the 1990s. The terms “DCS”, “PLC”, “PID”, “APC”, “Computer Control”, “Process Optimization”, “MPC”, “Model-Based Control” etc. are ubiquitous in process control literature. A prerequisite for APC/MPC success is a well-designed primary PID control platform with optimized tuning. Increasing application of advanced control schemes places higher demands on the skills and experience level of process control engineers and technicians. This paper describes some powerful practical process control software tools aimed at helping control engineers and technicians to design and implement control schemes inside the DCS for improving plant control. These tools and the methodology can help plants to maximize production rates, minimize utilities and increase the plant’s profits.
