摘  要：由于工作状况变动和建模误差等缘故，实际电机的精确模型很难得到。为使具有外界干扰以及模型不确定性的电机能够满足控制品质的要求，该文为一台无轴承交替极薄片电机设计了H∞鲁棒控制器。通过仿真研究，验证了所设计鲁棒控制系统可以有效地抑制外界干扰，具有良好的鲁棒稳定性，同时能够满足实际电机绕组电流幅值约束条件，所得结论为进一步开展实验研究奠定了良好的理论基础。

Abstract: The exact model of practical motor is difficult to gain due to its alteration of working states and model error, et al. In this paper, to make motor with disturbance and uncertain model satisfy all quality requirement, a H-infinity controller for the consequent-pole bearingless slice motor was designed, and the responses of the consequent-pole bearingless slice motor system under disturbance and model uncertainty were investigated by simulation model. Simulation results show that the H-infinity controller is able to equip the system with strong robustness, excellent disturbance attenuation performance and magnitude constraint of practical current, and lay a solid basis for further experiments research.
