On robust stability of uncertain neutral systems with multiple delays

This paper deals with the problem of robust stability of uncertain neutral systems with neutral, discrete and distributed delays. A method based on linear matrix inequalities is presented that makes it easy to calculate both the upper stability bounds and the free weighting matrices. Since the criteria takes three different delays of neutral-, discrete- and distributed-delays into account, it is less conservative than previous methods. Numerical examples illustrate the improvement this approach provides over previous methods.
