Goal:
reproduction of H-2 results of flexible structure using an H-infinity controller
Methodology:
To formulate a mathematical representation including disturbances and noise for the given linearized finite element model that was provided. Using Matlab programming, I was able to iterate on an optimization scheme to reach an acceptable disturbance attenuation and attain balance of robust stability
Original LQG controller:
H-inf design:
Conclusion:
Comparing this result to the LQG response in the original paper, we can see H-inf controller got rid of the small disturbances in the LQG design. The H-inf controller attenuated the disturbance response in the order of 10)9 at -23dB. We can see that the attenuation of the peaks has been significantly improved.
