In order to improve unsatisfactory effect of traditional identification methods for nonlinear systems
quantum-behaved particle swarm optimization( QPSO) algorithm is introduced to dynamic calibration identification of force transducers. A dynamic calibration facility with vertical sine force loading is built up. A sine mechanism is employed to generate sinusoidal motion in the facility
and dynamic force can be obtained based on determination of inertia force as a mass mounted on sine mechanism. To verify feasibility of QPSO for system identification
two groups of experiments are carried out. The results indicate that the identification precision of QPSO is superior to recursive least squares method
and it is feasible for nonlinear system identification.
