I am an earthquake engineer and I have an issue that I believe you can help me with.
As you know earthquake acceleration record and the structure response under this excitation is a signal. Now I want to control these signals with feed-forward and feed-back algorithms of active control.
So would you please introduce me to some brief sources that explain the basis of active control and optimal control of a signal and some sources which explain different types of feed-forward and feed-back algorithms?
