Title:
DAMPER CONTROLLER
Document Type and Number:
Japanese Patent JP3129335
Kind Code:
B2
Abstract:

PURPOSE: To lighten the influence of the friction in an active dynamic damper by adjusting the actional force generated in an actuator.
CONSTITUTION: An adder adds up the inertia, which is gotten by multiplying the acceleration a2 of a vibrator 1 by the mass m of auxiliary mass 2, and the state feedback quantity u from an adder 15 so as to find the external force working on the auxiliary mass 2 in ideal state. A subtracter 18 subtracts this external force by m so as to find the relative acceleration a1 of the auxiliary mass 2, and integrators 19 and 20 integrate it in order so as to find the relative speed calculated value V1' and the relative displacement calculated value x1' of the auxiliary mass 2. Subtracters 21 and 23 calculate the difference between the value X1' and the displacement X1 of the auxiliary mass 2 and the difference of the speed v1 of the auxiliary mass 2 so as to find the errors e and ev, and an adder 25 adds the value of having increased it by KP and Kd times with the subtracters 23 and 24 to it so as to find the correction ec. Furthermore, the value wherein the state feedback quantity u is added by the adder 26 is made the force to work on the actuator.
