Process Control Optimizer nv-ADCOP

What are the hidden values that can be brought out in your process control system?
For example, in water treatment plant added value may be achieved by minimizing the dispersion of pH concentration in a pool.
In a coal fired boiler it may be attained by stabilizing and increasing the main steam temperature within the operation range.
The improvement will bring both cost and energy savings for the plant owner.
nv-ADCOP helps you to bring this value-adding performance by providing the control function blocks for such applications, identifying the process parameters and optimizing the control ones.

Process Control Optimizer nv-ADCOP Front view

Features

nv-ADCOP Library for Advanced Applications

Provides advanced control function blocks that including MD-PID, (Model-driven PID), executes much improved control performance than conventional control and the other useful function blocks as well as samples programs for typical applications.

System Identification of the Target Process

Identifies the parameters of the specified processes by sampling a set of manipulated value, disturbance values and process values.

Parameter Optimization for the Target Controller

Optimizes the parameters of specified controller for the identified process. This is available for optimizing MD-PID as well as two-degree-of-freedom PID and conventional PI-D, eliminating manual tuning.

Application Example

Application Example

Applied PID algorism in nv-ADCOP Library

PI-D Control

PI-D Control

Is amongst the most common PID algorism which can be implemented in world wide DCS. Compared with conventional PID, the merits of PI-D are to prevent differential shocks to target process when the SV (set point value) is changed.

Two degree of freedom PID Control

Two degree of freedom PID Control

Is a type of two degree of freedom PID algorism developed by TOSHIBA. Compared with a general PI-D algorism, the merit of TDOF-PID is in its ability to optimize control performance for both set point change and process disturbance.

Model Driven PID Control

Model Driven PID Control

Is a type of IMC (Internal Model Control) algorism developed by TOSHIBA. Compared with PI-D, the merits of MD-PID are to provide optimal control for

  • long dead time process.
  • disturbance as well as set point changes.
  • various process dynamics.

Feed Forward Control

Feed Forward Control

Is a type of disturbance suppression algorism. DV (Disturbance Value) affect PV (Process value). The disturbance components of PV can be compensated by this FF control.
