Aiming at electro-hydraulic servo control system, the simulation model of fault self healing is studied and combine artificial immune system to self-healing for the purpose of making the electro-hydraulic servo control system feel their own status in the engineering applications. Some components faults and early breakdown can be recognized by using communication and coordination between its components...
The most widely studied linear models of the suspension forces in ac–dc three-degree-of-freedom hybrid magnetic bearings may not be practical for application to the precision control of bearings with larger air gaps for larger suspension forces. In addition, the simplified linear and the real nonlinear models in linear zone of current and displacements have not been compared before. In this study,...
A hybrid parameter extraction method for GaAs/GaN HEMT modeling is proposed. The electromagnetic (EM) simulation is integrated to de-embed the coupling effects of the extrinsic passive part of the device. By analyzing the coefficient matrix of de-embedded Y-parameters with rearrangements, the intrinsic elements values of HEMTs' small-signal equivalent circuit can be solved uniquely from different...
