A new efficient algorithm for the optimal implementation of sampling controllers with finite word length constraints is proposed: the optimal realization problem evolves into a nonlinear programming problem, which can be solved by using the existing optimization techniques. Theoretical derivation and numerical examples show that The calculation of the algorithm is simple and convenient, and the optimal realization results obtained have more stable boundaries and shorter stable word length than the previous ones.
