Ob opredelenii koeffitsientov kvadratichnoy funktsii Lyapunova s zadannymi svoystvami v sluchae kratnykh korney kharakteristicheskogo uravneniya

Abstract

For continuous and discrete linear autonomous systems, we discuss the possibility of choosing the coefficients of the quadratic Lyapunov function that ensure the validity of the condition of sign-negativity of its first derivative (first difference) with a given margin in the case of multiple roots of the characteristic equation.
