I am using direct synthesis to design a controller for an open loop unstable processes. G(s) = k/(s-a) and I think I need to stabilize this by adding a feedback loop before applying direct synthesis. But I am not sure what kind of feedback loop I can add. Please help. Thanks.
Dear Saeam Kim,
We can use many different methods for system stabilization:
Pole assignment stabilization using state feedback, compensator feedback, Observer feedback and so on.
I suggest to you attached files in topicss.
Best regards
Dear Kim
If the system is controllable, the linear quadratic regulator can be applied to the system.
The regulator is robust and easy to design by MATLAB.
Hi
You can simple explore following for direct synthesis..
1. IMC design
2. PI-PD structure, PD in feedback with unstable process
Dear kim
Prefer mu based direct synthesis for such type of analysis.
IMC is good but prefer Optimal IMC based PID controller configuration for it.
