The research of an active vibration protection system of precision opto-mechanical complex subjected to random kinematic effects from the foundation has been carried out. As an actuator in the system a magnetorheological damper has been used. For the system operating in conditions of random disturbances with varying characteristics, the rms criterion has been adopted as an optimization criterion. According to the SPSU Professor Yu.P. Petrov’s method a guaranteeing controller has been synthesized and on its bases meeting the requirements of physical realizability, a quasi-guaranteeing regulator has been obtained. A comparative analysis of the optimization criterion’s variations in a closed system with optimal, quasi-optimal, guaranteeing and quasi-guaranteeing regulator in terms of parameters disturbance has been performed. The recommendations for the rational areas of use of the considered regulators have been given.


Keywords: random disturbance, power spectral density of disturbance, active vibration isolation system, magnerheological damper, optimal regulator, guaranteeing regulator.
