PID or not PID ! Relaxc ?

Relaxc is a new approach of process control .  I would like to have a feedback on the use of relaxc.

There's a free trial (on shop.exchange.se.com) .

 

 Relaxc is easy and quick to use with respect to PID control : just identify the delay or gap time and the maximum speed of the process. The documentation (Practical tuning of relaxc) gives all the information to identify 2 coefficients and calibrate the 3rd , but I remain available to help if necessary.

 

  If 2 ou 3 people  have the opportunity to test relaxc on a real case, for example by replacing a control as  PID,IMC, predictive control or other by relaxc, I would like to have their try results or comparisons   in terms of response time, behavior of rejection of disturbance,  ease of use, energy cost. the  results can be shared here.

 

 Otherwise I would like to have the list of process control training centers that works with Expert control software  that would have test benches to try  it.

  Thank you for your help.

Re: PID or not PID ! Relaxc ?

Hi

For a better understanding of Relaxc, here are the slides

and a link to a trial version of relaxc under simulink to test which allows to replay  all the examples of the practical tuning of relaxc.

 ask me code for one month or more
