RangO, i guess Martin has problems on choosing control loops, not on implementation itself. Although i can be wrong |

Yes and a good idea to put the control neutralization will apply this theory, but before hand follows the assembly program as an example of the cascade, see if this coherent extruded.

Could you explain what kind of feedforward did you use? What was the final version of your regulation loop? |

IS IT only only possible to control one single output variable through two no of PID controls. |

Hello again, Of course that is possible: Attachment:Cascade.zip (132 Downloads) and the snapshots: Attachment:result.zip (96 Downloads) Provide what kind of process you want to control, to see if this structure is helping. Best regards Hamid Hosseini |
