针对一台1kW、18000 m in-1双锥形无轴承永磁同步电动机样机，提出了基于全模态综合的运动解耦积分作用极点配置控制方法。对样机的机电模型进行了解析推导，并进行了控制方案的设计。推导了具有积分作用和运动解耦的极点配置方案的设计，以及Luenberger观测器的设计。控制方案中集成了多变量不平衡力抑制滤波器，以防止执行器过载。在试验台上测量了不同运动情况下的闭环系统性能和灵敏度函数，并与其解析表达式进行了比较。最后演示了额定速度下的运行情况。
The pole placement control with motion decoupling and integral action, according to the full modal synthesis, is addressed in this paper, to control a 1 kW, 18000 min-1 double conical Bearingless Permanent Magnet Synchronous Motor prototype. An electro-mechanical model of the prototype is derived analytically together with the design of the control scheme. The design of a pole placement scheme, with integral action and motion decoupling, is derived, as well as the design of a Luenberger observer. A multi-variable imbalance force rejection filter is integrated in the control scheme, to prevent actuator overloading. The closed-loop performances as well as the sensitivity functions, for the different motions, are measured on a test-bench and compared to their analytic expressions. Operation at nominal speed is finally demonstrated.
