Abstract :
The closed-loop system with a state-estimate feedback controller is described, and error feedback circuits are incorporated into the state-estimate feedback controller. The optimal closed-form solutions of error feedback coefficients are presented to minimize the output round-off noise of the closed-loop system, under l2-norm scaling constraints in the state-estimate feedback controller. Finally, a numerical example is given to illustrate the utility of the proposed technique.
