零功率控制应用于混合极性双并联磁悬浮系统。最基本的磁悬浮系统由悬浮物体（浮子）、电磁铁和功率放大器组成。在双并联磁悬浮中，两个浮子和电磁铁由单个功率放大器控制。讨论了混合极性双并联磁悬浮零功率控制的可行性。分析表明，零功率控制器系统可控的条件与极性无关。实验证实，均匀极性和混合极性悬架系统均可实现零功率悬架。
Zero-power control is applied to a double parallel magnetic suspension system with mixed polarity. The most basic magnetic suspension system consists of a suspended object (floator), an electromagnet and a power amplifier. In double parallel magnetic suspension, two floators and electromagnets are controlled with a single power amplifier. The feasibility of the zero-power control in double parallel magnetic suspension with mixed polarity is discussed. It is analytically shown that the condition for the system with a zero-power controller to be controllable is independent of the polarity. It is confirmed experimentally that the zero-power suspension is achieved in both uniform-polarity and mixed-polarity suspension systems.
