摘要
圆锥形电磁轴承—转子系统结构简单,但控制复杂,为此,本文首先提出圆锥形电磁轴承系统的五电流差动控制方案,建立系统动力学模型,在此基础上,针对系统参数不确定,并受到不确定性扰动问题,文中采用了一种具有鲁棒特性的时间滞后(TDC)控制规律,通过仿真分析、比较了TDC控制与普通最优PD控制对圆锥形电磁轴承系统性能的影响。
The structure of the conical bearing system is simple, but the control is complex. Because of this, in this paper, a five-current differential control of the conical bearing system is put forward and the model of system dynamics is built. Based on this, aiming at the change of the parameters and the unexpected disturbances of the conical bearing system, Time Delay Control (TDC) with robustness properties is applied. By means of the simulation analysis, the effects of the TDC on the conical bearing system are compared with those of the common optimum PD controlling.
