According to the theory of automatic control, there should be no behavior's difference between an object given by a set of transfer functions, which are respectively interconnected, and a real object, corresponding to such a theoretical structure with given transfer functions. Accordingly, a generalized analysis of the Otto Smith hypothesis regarding the stability indices in automatic control systems with unstable zeros and poles of second-order transfer functions is carried out.

Nowadays, one of the main tasks is the development of alternative energy. Despite the considerable number of advantages, such sources of energy as the sun and wind are not permanent, and since these sources naturally work in "antiphase" it is advisable to use them together. Also, due to their instability, they are typically used with various types of storage systems, in particular hybrid energy storage systems, such as a combination of batteries and supercapacitors, which have better performance.
