Research of the effectiveness of the active vibration isolation system with different types of regulators

In article comparison of effectiveness of active vibration isolation system with various types of regulators is carried out. On the basis of received earlier in other articles of authors of analytical dependences in the form of transfer functions of links of system of automatic control of vibroprotection the regulator providing a desirable type of the logarithmic amplitude-frequency characteristic of the closed system is synthesized. On the basis of received earlier in other authors articles of analytical dependences in the form of transfer functions of object of vibration isolation system the regulator providing a desirable type of the logarithmic amplitude-frequency characteristic of the closed loop system is synthesized. Efficiency of the closed loop vibration isolation system at action of the random disturbance with variable parameters is estimated by the accepted square criterion of quality. Comparison of the received calculated data of the adopted criterion of quality with using optimal and the regulator providing a desirable form of the logarithmic amplitude-frequency characteristic of the closed loop system is carried out.
