Before a few weeks ago I was new to ANSYS and FEM analysis. Now I've learned myself to do some modal, harmonic, transient, psd analyses with a simple plate (1x1x1e-3m with properties of steel). I'm doing this as I'm graduating in Electronic Engineering & Design on the subject of active vibration control on a particular structure. After succesful simulations I will be working on a real test setup with prototype of actuator and microcontroller.
After doing all the standard analyses such as modal, harmonic, etc. I now want to start working on some active control. I found a few examples using piëzo actuators which can be found in ANSYS's elements library. However, my actuator will be a shaker-type actuator (comparable to a loudspeaker).
I'm wondering how to build this. I think of COMBIN14 w/ MASS21, but can I add a PID-like controller?
I'm not neccessarily looking for a worked out solution, but som tips from where I can start would be very welcome.
What I'd like to do is this:
1. build the structure
2. constrain, etc.
3. apply psd (I have measurements/freq-spectrum of vibrations through the real structure).
4. apply actuator with active vibration control
5. setup PID-controller
6. test different PID-values and actuator positions on the structure to find best spot.
7. use the above values/position as a starting point for prototype test.
