Abstract
In the paper the characteristics system and efficiency of a closed-loop vibration protection with an executive electromechanical element in the form of a linear DC motor (LDCM) are considered. Based on the presented calculation model, with necessary assumptions, mathematical models of the vibration protection system in the form of transfer functions along the control and disturbance channel are. The structure of the active vibration protection system including LDCM, controlled converter, accelerometer sensor of the protected object and regulator is developed. Taking into account the developed mathematical models and the developed structure of the active vibration protection system, the analysis of the system's characteristics by simulation has been carried out. The obtained results of the analysis allowed to estimate the effectiveness of the vibration protection system in a closed and open state. Taking into account the requirements for the dynamic characteristics of a closed-loop system, a regulator is synthesized. Recommendations on the use of an active vibration protection system are formulated.
