<P>PROBLEM TO BE SOLVED: To accurately estimate a dual inertial mechanical model including a total inertial moment and a damping coefficient in a mechanical system including a motor 1, a load 2 and a coupling shaft 3 by the small quantity of computation. <P>SOLUTION: A frequency amplitude characteristic ¾G<SB>M</SB>(jω<SB>s</SB>)¾ of a motor speed ω<SB>M</SB>to a torque of the motor 1 is multiplied by a corresponding angular frequency ω<SB>s</SB>, and a mechanical resonance characteristic ¾G<SB>M</SB>(jω<SB>s</SB>)¾ω<SB>s</SB>is acquired. Local maximum/local minimum point coordinates are used, and a parameter h is introduced so as to calculate an anti-resonance angular frequency ω<SB>a</SB>and the damping coefficient ω<SB>a</SB>. The total inertial moment (J<SB>M</SB>+J<SB>L</SB>) of the dual inertial system mechanical model, a spring modulus K<SB>F</SB>of the coupling shaft 3 and a viscous friction coefficient C<SB>F</SB>are analytically derived. <P>COPYRIGHT: (C)2007,JPO&INPIT |
