Abstract

Designing a controller usually involves several iterations between the synthesis based on a set of parameters, the analysis of the robustness and performance obtained so far, and correction of the design parameters. An approach based on Computer-Aided Design is proposed, where the engineer manipulates the graphics with a mouse, sees immediately how the performance changes, and feels how the different objectives are linked. The instantaneous performance display enables understanding the problem better and obtaining a satisfactory compromise. Applications to research and education are described. Copyright 1999 IFAC
