| Abstract: | Based on hybrid suspension of electromagnets and permanent magnets system,the linear design of zero power suspension controller is realized. The current integral item is independently controlled by the external loop. Its current feedback adopts the top speed current loop theory. Then,the loop current could track and control the voltage variety in high speed,and decrease the inductance hysteresis. The adaptive mechanism of PD loop parameters under varied load quality conditions is designed according to the corresponding optimal control parameters of varied load quality and its corresponding clearance when realizing the zero power suspension. |
