Jointly optimized error-feedback and realization for roundoff noise minimization in state-estimate feedback digital controllers |
Abstract | ||
|---|---|---|
The joint optimization problem of error-feedback and realization for the closed-loop system with a state- estimate feedback digital controller is investigated where the main objective is to minimize the effects of round- off noise at the closed-loop system output subject to l2-norm dynamic-range scaling constraints. It is shown that the problem can be converted into an unconstrained optimization problem by using linear-algebraic tech- niques. The unconstrained optimization problem at hand is then solved iteratively by employing an efficient quasi-Newton algorithm with closed-form formulas for key gradient evaluation. Analytical details are given as to how the proposed technique can be applied to the cases where the error-feedback matrix is a general, di- agonal, or scalar matrix. A numerical example is pre- sented to illustrate the utility of the proposed technique. |
