  Vecta on Advanced Process Control
Technology has revolutionised process control.

Process Automation Systems incorporate the memory, processor and software technologies developed in the PC industry which now allow users to apply a range of advanced techniques to supplement the more traditional, essentially, single linear variable PID, ratio, and feedforward control.


APC facilities typically include:

  • multi-variable control (MVC), in which several variables are used to compute the required level of control;
  • on-line batch scheduling and automation, in which production is automatically scheduled to take account of orders, available equipment and materials against specific business objectives and constraints;
  • non-conventional advanced control, in which plant behaviour is compared to a model and rules applied to bring plant behaviour closer to that required;
  • dynamics control, in which the true transfer function of a plant unit is modelled so that precise control can be achieved; especially useful in extending life, reducing energy consumption, or improving precision of rotating machinery;
  • matrix control, a more extreme form of multi-variable control where a range of measured variables and controls are all assumed to affect the process outcome to some degree;
  • statistical process control (SPC), in which statistical techniques are used to detect and correct potential deviations from desired performance;
  • alarm management, in which patterns of deviations are analysed in order to identify and focus operator attention on, the prime cause of an alarm;
  • operator advice, in which patterns of process measurements are analysed and translated into advice on appropriate rectification actions by operators.
  Deployment of advanced process control is often accompanied by use of special-purpose or application-specific sensors or on-line analysers.

Business management can also be improved by use of Manufacturing Execution Systems (MES) to integrate information from enterprise and plant level systems and incorporate features such as order processing, production scheduling, resource management, customer relationship management (CRM), asset and inventory management, formulation (recipe) management, predictive maintenance.

  Use of advanced process control techniques can significantly increase output, improve quality, and reduce both product and plant whole-life costs but selection, deployment and maintenance can be difficult.

Our Process Automation Experts Network is dedicated to exploring developments in process automation and enterprise integration. This involves projecting the evolution of enterprise and plant level functionality and identifying strategic business needs. It also requires identifying issues related to supplier and partner selection.


Our extended network ensures we have the expertise to help you solve just about any business or technology problem.
