标题：NLControl – a Mathematica Package for Nonlinear Control Systems * * The research was supported by the Estonian Research Council, personal research funding grant PUT 481
摘要：AbstractThe paper describes a symbolic computation software package NLControl, dedicated to the study of various modelling, analysis, synthesis problems for nonlinear control systems. Most of the developed functions are based on algebraic approach of differential forms, and on the theory of non-commutative polynomial rings. For a few control problems an alternative solution is implemented in terms of functions algebra. The package addresses both continuous-and discrete-time systems as well as systems, defined on homogeneous time scales. Comparison of NLControl and Mathematica built-in nonlinear control functions is given.
