Among the huge number of different designs of speed and power regulators of low-power wind turbine rotors, centrifugal regulators take priority. In theoretical terms, mathematical models of centrifugal regulators were developed, based on which the questions of statics and dynamics of the regulation process were considered. The profile of modern blades for wind turbines is close to the calculated maximum, that is, its expansion from the end to the blade shank is from 1:2 to 1:4 and the twist is up to 30°. This causes a deviation of the direction of the moment of inertia of the blade from the chord of the blade by up to 20°, which was taken into account in the latest mathematical models of the centrifugal regulator of the wind turbine rotor. Given that dynamic loads can lead both to a decrease in the accuracy of regulation and to the destruction of individual components of the regulation system, there is a need to clarify dynamic processes in the regulation system. In this work, the conditions of stability of the wind turbine rotor control system with a centrifugal regulator for weather vane and anti-vane control are specified, taking into account the angle between the chord of the blade and its moment of inertia vector.
