Partial Cylindrical Algebraic Decomposition for quantifier elimination
George E. Collins,Hoon Hong +1 more
TL;DR: This paper presents a method which intermingles CAD construction with truth evaluation so that parts of the CAD are constructed only as needed to further truth evaluation and aborts CAD construction as soon as no more truth evaluation is needed.
Journal ArticleDOI
Real-Time Calculation of Switching Angles Minimizing THD for Multilevel Inverters With Step Modulation
Yu Liu,Hoon Hong,Alex Q. Huang +2 more
TL;DR: A novel real-time algorithm for calculating switching angles that minimizes total harmonic distortion (THD) for step modulation is proposed and a mathematical proof that the output voltage has the minimum THD is given.
Proceedings ArticleDOI
An improvement of the projection operator in cylindrical algebraic decomposition
TL;DR: By generalizing a lemma on which the proof of the original projection operation is based, this paper is able to find another projection operation which produces a smaller number of polynomials.
Journal ArticleDOI
An efficient method for analyzing the topology of plane real algebraic curves
TL;DR: A practically efficient algorithm for analyzing the topology of plane real algebraic curves is given, which produces a planar graph which is topologically equivalent to the real variety of the polynomial on the Euclidean plane.
Journal ArticleDOI
Testing Stability by Quantifier Elimination
TL;DR: This paper shows how to write all common stability problems as quantifier-elimination problems, and develops a set of computer-algebra tools that allows us to find analytic solutions to simple stability problems in a few seconds, and to solve some interesting problems in from a few minutes to a few hours.
