WEBMATHEMATICA BASED TOOLS FOR CONTINUOUS-TIME NONLINEAR CONTROL SYSTEMS

The package NLControl, developed in the Institute of Cybernetics at Tallinn University of Technology within Mathematica environment, has been made partially available over the internet using webMathematica tools. The package consists of functions that assist the solution of dierent modeling, analysis and synthesis problems for nonlinear control systems, described either by state or by input-output equations. This paper focuses on describing the webMathematica-based tools for continuous-time nonlinear control systems.
