In this paper, a novel decoupling control approach based inverse system and internal model methods are presented to improve the dynamic properties accuracy of reluctance type bearingless motor (RBLM) effectively. By employing method, we can obtain decoupli ng pseudo-linear system, which consists two second-order linear integral subsystems one first-order subsystem. addition, reject influence unmodeled dynamics as well enhance RBLM robustness, 2 degree-of-freedom (DOF) is used for three...
In this paper, we summarise our recent results in fault tolerant formation control of Unmanned Air Vehicles (UAV). A scheme to deal with both GPS sensor failure and wireless communication packet losses is presented. Moreover, some extensions the algorithms developed by UC Berkeley are made support time-varying heading curved flight trajectories. The effectiveness presented illustrated real-time simulations conducted a network environment. Both rotary fixed wing UAVs, mesh triangular...
In this study, the process and utility water requirements for cellulosic ethanol production via fermentation pathway were assessed on a volume‐to‐volume basis (i.e., gallons of consumption per gallon production) using data reported in literature. The analyzed combination three feedstocks hardwood, corn stover, switchgrass) two pretreatment technologies dilute acid ammonia fiber expansion) under different network configurations aiming zero wastewater discharge. results indicate that...
For the demand of high speed and accuracy, use active magnetic bearing (AMB) plays a key role in various industries such as clean rooms, compressors satellites due to their contactless nature. In this research, two other control options for machine were designed based on optimal output feedback H∞ methods improve radical axial position regulation AMB. The gain matrix with minimum performance index is obtained by solving Riccati equation fed back system order achieve system’s performance....
The permanent magnet synchronous generator (PMSG) is investigated and its mathematical model established in two-phase rotating coordinates. Aiming at the fact that PMSG may present chaotic behaviors certain values of parameters under working conditions, output feedback control gain matrix with minimum performance index obtained by solving Riccatic equation fed back to system order improve considering disturbance.

Because a rotor has no permanent magnet and low manufacturing cost, bearingless switched reluctance motor (BSRM) unique advantages in medical health, biochemical reactions, other applications that need to be abandoned after single use or require the system deal with high-temperature fluid. By analyzing topological characteristics of BSRM, suspension mechanism operation were described. A finite element model BSRM stator yoke (BSRM-PMSY) was established. The performance analysis emphasized....
