AN EXPERT-SYSTEM FOR MULTIVARIABLE CONTROLLER-DESIGN

In this paper a software package for the design of decentralized and c entralized multivariable controllers is described. The software packag e includes several numerical methods for multivariable controller desi gn as well as an expert system to assist the user. The user interface of the expert system employs hypertext techniques. A continuous-time t ransfer function matrix is used as a process model. When the process m odel is known this software package can be used to select a control st ructure and to tune controllers. The paper first describes the differe nt subtasks of multivariable controller design. Next a short descripti on of the design and analysis methods included in the software package is given. A description of the expert system and a design example fin ish the paper.
