英文摘要

      This paper presents two kinds of implicit self-tuning controllers with on-line choice of weighting terms combining self-tuning controller and pole-zero placement strategy. The choice of weighting polynomials and the self-tuning controllers are implemented in implicit scheme. i.e. the weighting polynomials and controller parameters are estimated using only input-output data. It is proved that the two kinds of self-tuning controller have global stability and convergence properties. The simulation examples demonstrate the effectiveness of thd algorithms proposed.
