'''Vasile Mihai Popov''' (born 1928) is a leading [[system theory|systems theorist]] and [[control engineering]] specialist. He is well known for having developed a method to analyze [[stability theory|stability]] of nonlinear [[dynamical systems theory|dynamical systems]], now known as [[Non-linear control#Popov criterion|Popov criterion]].

=== Hyperstability ===
In the early 1960s, Popov also conceived the notion of [[hyperstability]], a concept that he viewed as generalization of [[absolute stability]]. This introduced a new and a very fruitful point of view for the analysis and synthesis of nonlinear feedback systems. 

This research work was published in the first half of the sixties and led to the book ''Hyperstability of Dynamic Systems'', first published in Romania in 1966, and subsequently translated in
to French and English ([[Springer Science+Business Media|Springer-Verlag]], 1973). Popov was also the first to discover the geometric invariants of linear systems with respect to certain "transformation groups" and he introduced a "canonical" form for uniquely describing the multivariable systems.
