摘 要：Based on the analysis of the model of the Single-Degree-of-Freedom (SDF) magnetic bearing system,the issue of design and simulation of PD control strategy in the system is investigated.First,the plant model of the AMB (Active Magnetic Bearings) with Single-Degree-ofFreedom (SDF) is found out to be unstable plant.Then,based on the root locus theory and Routh stability criteria,the necessity of derivation action in the controller is analyzed.In addition,the PD control strategy for a particular plant is designed,the effectiveness of which is validated by the given simulation examples.The proposed approach can provide an important reference for the practical application of PD control strategy in the magnetic bearing system.
