Servo gain calculation manner, the servo gain calculation device which possesses the servo gain

摘要

PROBLEM TO BE SOLVED: To provide a method, a program, and a device for computing servo gain for easily computing a servo gain without requiring highly specialized knowledge.;SOLUTION: In calculation of the servo gain for a feedback control system using a transfer function having ideal characteristics corresponding to that for the feedback control system, a transfer function for the feedback control system and the transfer function having ideal characteristics are equated, and a simultaneous equation about coefficients for a Laplacean operator is obtained. From this simultaneous equation, a conditional expression for the coefficient giving a positive real solution is found, while various constants for the feedback control system are decided. When the decided various coefficients are assigned to the conditional expression for the coefficient giving the real solution, the servo gain for the feedback control system is calculated.;COPYRIGHT: (C)2007,JPO&INPIT
