摘要：
In order to realize high speed motion control with high precision, the load characteristics of the chopper disk were analyzed, and the mathematic model of the controlled object, which was a two-mass model composed of disk entity and drive motor, was established. Based on this model, a current-speed-position cascade controller was designed, and the select method of the adjusters' structure and parameters was given, based on the engineering design method and modern control theory. With a rotation frequency of 27.5 Hz, the position perturbation error ranged from -1.325 25 μs to 1.325 25 μs, and the steady-state error was -2.583 μs, which met neutron chopper's application requirements. ©, 2015, Editorial Office of High Power Laser and Particle Beams.
