We consider the basic possibility of constructing an active vibration isolation system with extreme control system electro-dynamic actuator on the basis of information from the accelerometer and the force sensor. It is shown that the switching on of the actuator that produces force proportional to the acceleration of the inertial mass parallel passive vibration isolation system of equivalence of inertial motion transducers. The analysis of the effectiveness of such a system of vibration isolation is given and offered the option of building extreme regulator (using information from the force sensor), is offered which provides automatic adjustment of the minimum transmission of force to the body at an arbitrary frequency harmonic disturbance. Promoted analysis of vibration isolation system with extreme regulator with input action in the form of broadband noise and the line spectrum is performed. Simulation of system with extreme control program in MATLAB / Simulink is undertaken. The research has shown that the proposed active system with extreme vibration isolation controller increases the efficiency in a given frequency range both in the single-frequency harmonic action, and when exposed to the sum of broadband random noise and the line spectrum, and both dispersion forces transmitted to the body, and the amplitude of the line spectrum frequencies in comparison with the passive system reduces greatly.
