We designed some new filters for the low bandwith CHARD Yaw at 40W.

We plan to lower the gain for about 6dB, which will give us a UGF at 3.5Hz and use the new filters 6 ('40W') and 7 ('ctrlHBW') to stablize the loop (blue curve in the 2nd Figure). The new cutoff filter for 40W is filter 9 ('cutoff40W') (Figure 1). The pink curve in the second curve is what we expect from the simulation.
