ABSTRACT:Objective To identify the acceleration control model of a centrifuge and to carry out the simulation and optimization of the control system. Methods The speed, voltage and current during the running of a centrifuge were measured, and the relationship between the armature current and the speed was fitted at speeding up and speed-hold states. Then the model parameters of load resistance and equivalent inertia were analyzed. The Simulink simulation model of the centrifuge acceleration control system was established. Results The simulation results of the model based on identified parameters were close to the results of the real system test, providing a credible model for the optimization of control system, estimation of various test ability and control error. Conclusion The identification method is feasible and the parameters are correct and the running of centrifuge simulation model is fast and correct, which can be used for the identification and simulation of the centrifuge.
