Most colleges and universities worldwide are still teaching Laplace transforms, Laplace domain, frequency domain, Bode plots, Nyquist stability criterion, Ruth Hurwitz criterion, discrete domain, poles and zeros in transfer function models, Ziegler Nichols tuning method, ARX – auto regressive models with exogeneous inputs, ARMAX – auto regressive moving average models with exogeneous inputs, Box-Jenkins method and the use of Matlab with Simulink from Mathworks.
The above topics and tools are unfortunately outdated and do not help the control engineer or DCS technician or PLC technician in the modern control room environment in chemical plants and factories.
Laplace domain is a method to convert ordinary differential equations into algebraic equation, so the solution is easier. This was useful and relevant before the widespread use of computers in the 1980s. Today, it is easy to solve differential equations using Euler method or Runga Kutta method and there is really no need for using Laplace transforms in a undergraduate or even graduate course on process control taught under chemical engineering, mechanical engineering or electrical engineering disciplines.
Matlab is not used in the control room environment at all. Matlab is too bulky and too complex for undergraudate teaching and even for graduate courses.
PiControl Solutions LLC and AIAPC – Americal Institute of Automation and Process Control are offering amazing new teaching material perfect for both undergraduate and graduate teachings in process control. We cut out the old and obsolete process control material and teach modern methods using modern software and algorithms that new engineers and technicians can start using immediately in the control room environment.
The three-unit combo comprising of PITOPS, SIMCET and PiProMaster cover primary process control, PID tuning, Advanced Process Control and practical applications in a new and modern manner, very effective, hands-on and practical. Please see:
