Magnetic suspension system is a typical non-linear hysteretic system. A kind of technology, which combines the permanent magnet and the electromagnetism, is presented for its characteristics and can obviously reduce power consumption. In order to solve the impact of the change of current in magnet coils on the overall rigidity, a double closed loop control system, which introduces the current loop...
The requirement of the stiffness of the magnetic suspension beams in Large Gantry Machining Center is different from that of the magnetic suspension trains and other magnetic suspension devices. According to its characteristics, a kind of suspension technology, which combines the permanent magnet and the electromagnetism together, is presented and could obviously reduce power consumption. In order...
Magnetic suspension platform system (MSPS) is a typical non-linear and hysteresis system, so itpsilas difficult to obtain the precise mathematic model and to cater the requirement of rapidity, stability and robustness by applying traditional PID or fuzzy controller separately. Aimed at the characteristics of MSPS, a composite control model combining PID with fuzzy (P-fuzzy-PI) is introduced by applying...
