摘要
定义了磁力轴承支承在时间域的刚度与阻尼和在频率域的广义刚度 ,建立了两者之间的联系 ,结合PD、PID控制规律推导出磁力轴承刚度与阻尼的计算公式 ,建立了轴承刚度、阻尼与控制系统参数之间的联系 。
Stiffness and dampness of active magnetic bearings in a time and frequency domain are defined. Formulas to calculate this stiffness and dampness by using PD and PID controllers are deduced. Relationship between the stiffness, dampness and control parameters are established and the effect of control parameters on the supportive property is analyzed.
