CAD package L-A-S: a research and education tool in systems and control

A review is presented of the basic features of the high-level interactive language L-A-S (linear algebra and systems) used in CAD (computer-aided design) of linear control systems. Modular structure of the language permits easy modifications, updating and extensions. The language is implemented on mini- and microcomputers. The use of the L-A-S is illustrated on the typical LQG/LTR (linear quadratic Gaussian/loop transfer recovery) synthesis problem.<
