Contek Systems - Process Control Consultancy

Control engineering consultant for the oil and gas industry. Process control, de-bottlenecking, compressors, slugging and control system PID tuning. - John Greene

Observing Process Data by Contek Systems Ltd

"The root-cause of many control problems can be rather more subtle than poor PID tuning: see this tutorial for a selection of some control-related problems solved by Contek over the last few years."

U-Tune Tuning Calculator

Calculate proportional-integral tuning parameters for process controllers using the results of an open-loop step response.

The calculator supports the common controller algorithms and parameter types and provides two sets of parameters, one for fast and the other for slow responding loops.

Library of electrical models (analog, digital, machines, multi-phase) Information

This library contains electrical components to build up analog and digital circuits, as well as machines to model electrical motors and generators, especially three phase induction machines such as an asynchronous motor.


They create specialized software tools for engineering. The product suite includes Maple, the technical computing and documentation environment, and MapleSim, the high-performance, multi-domain modeling and simulation tool for physical systems.

Maplesoft is a subsidiary of Cybernet Systems Co. Ltd. in Japan.

Mathcad - Engineering Calculations

PTC Mathcad - Engineering Calculations

Mathcad is used to perform, document and share calculation and design work.
"The unique Mathcad visual format and scratchpad interface integrate live, standard mathematical notation, text and graphs in a single worksheet"

PTC Mathcad combines the ease and familiarity of an engineering notebook with the powerful features of dedicated engineering calculations application. Its document-centric, WYSIWYG interface gives you the ability to solve, share, re-use and analyze your calculations without having to learn a new programming language.

PTC Mathcad - Engineering Calculations

Some Features are -
  • Easy to learn and use - no special programming skills required
  • Increases productivity, saving engineers time and reducing errors
  • Improves verification and validation of critical calculations
  • Complete documentation of calculations supports standards compliance
Ideas, Design, Simulation, Emulation and Testing. The fundamentals are governed by Math. The parameters, the metrics, the limits, the specifications. All have to be taken into account, none overlooked.

More Meticulous and exhaustive the pre-processing is, the less errors and shocks we get at the end of the product design cycle.

I have had my share of jolts, the only reason being, i did not anticipate that jack in the design engineers design box. Remember Murphy is always looking.


Here is a tool Mathcad and a module for EE. That helps us in our design goals. Standard calculation procedures, formulae and reference tables used by electrical engineers.
