open-loop and closed-loop controls are of necessity treated separately because the sensitivity functions are different for each case. The optimal control based on the closed-loop Bode sensitivity is ...

and risk-sensitive cost function. Furthermore, we would relate the cost cumulants with information theoretic entropy, and Bode integral. The interpretation of cost cumulant control is given in terms ...

Transfer functions of linear systems, block diagrams and signal flow graphs. Sensitivity ... frequency response as polar plot and Bode diagrams. Closed loop frequency response. A control system design ...
