An intelligent front end for the H∞ controller design

An intelligent front end for the H_∞ control system design method is described. Systematic procedures for the H_∞ controller design are presented, and they are applied to the control system design of a single flexible link. The authors´ approach provides a coupling of the design knowledge and design algorithms for carrying out the controller design. Design knowledge of the systematic procedures involved has been represented in the knowledge-based development environment of the MEDAL control system design package. The algorithmic procedures for numeric processing are represented as user-defined functions (M-files) in the same control system design package. Hence, MEDAL provides a novel design environment which enables both heuristic and algorithmic knowledge to be integrated for H_∞ control system design
