aeSolutions process control specialists solve problems with Advanced Regulatory Control (ARC) when single variable PID control is not adequate.
Cascade, feed forward, ratio, Smith predictor, and override controls are standard methods to include an additional process variable in PID loops to compensate for process dead time, or non-linearity.
Multivariable and model-based controls are employed for more complex process automation challenges encountered in chemical plants and refineries.
aeSolutions helps the client's process engineers take advantage of the multivariable control capabilities found in the latest generation of DCS systems. These offer real time performance with multivariable models available at the controller's function library level.
