Hi,
I am a little nervous when I write this, it can be the start of a timeconsuming involvement. But it has been on my mind for a long time. And a recent thread (http://www.plctalk.net/qanda/showthread.php?s=&postid=51903) persuaded me to try to see if there are others that could be keen to pick up the topic.
Here goes:
PIDs can be implemented in PLCs to control processes of various kinds. But PID is not enough in many cases. More advanced methods could be applied such as implementing modelbased controls.
Models could be automatically determined in the PLC.
And control could be applied by means of the model.
But all comercially available modelling software is expensive and PC based (or DCS based). I would like to avoid PCs alltogether from the control loop.
PLCs gets more powerful (more memory, faster processing, more advanced programming capabilities), so the idea of putting the whole thing in the PLC enters my mind.
Are anybody interested in creating a "studying group" with the aim to develop program libraries and techniques for modelbased controls ?
Any takers
