Abstract
In the present paper intelligent control systems, based on fuzzy logic technology, automatic control system with fuzzy P-regulator in particular, are discussed. According to the investigation of transformations, going on in such regulators, they all actually are nonlinear and that particular explains improvement of control in automatic control systems with fuzzy regulators. Through the use of V.M. Popov's criterion the research of equilibrium absolute stability and system's processes are carried out. Relying on harmonic balance method, an equivalent complex amplification coefficient for nonlinear characteristics, implemented in fuzzy P-regulator, is established, whereby semigraphical method of indirect qualitative assessment is further formed. This method is sufficiently precise and convenient for analysis of automatic control system with fuzzy P-regulator and appears to be quite practical synthesis tool for nonlinear transformation in fuzzy regulator.

Key words
Fuzzy P-regulator, fuzzy regulators synthesis, harmonic balance method, indirect qualitative assessment.
