self tunable PID controller
显示 更早的评论
Hello All, I want to ask something about self tuning, in my model the load and also the airgap of transformer is changable for that reason, transfer function is not the same for all conditions, what is the best way to make coefficients of PI controller programmable, to find out stable controler parameters for any specific operation region, thanks in advance for any suggestion

Hi, Unfortunately there is no "off the shelf" solution for this scenario. There are a couple of options:
1. If dynamics is changing slowly with operating condition, you might tune at different operating conditions and then gain-schedule controller gains. A few steps of this approach are shown in this video.
2. I f you really want "adaptive" control, with some sort of onboard tuning, you will have to implement it yourself, it has been done in the past. You might want to search through MATLAB Central and through File Exchange.

If you know your operating points you can gain schedule different PIDs:
If you are looking for more of an online solution then try the MPC Toolbox:
