Based on the proposed flux observing method, a novel speed estimator has been designed. At last, the speed estimator combined with the flux observing is applied in the direct torque control system without speed sensor. The simulation results show that these methods can improve the accuracy of speed observing and the low speed performance of direct torque control system, and strengthen the robustness of system.展开更多

The results provide further evidence in support of earlier indications of a wave-only reality in which the quantum energy packet exists in the form of a conjugate wave—particle doublet. It reveals that matter, be it wave or particle, is a harmonic oscillator defined with full spectrum of the usual mechanical properties of simple harmonic motion SHM. Notably, the quantum energy packet’s stress field correlates with radius to generate intrinsic torque, it motivates spontaneous rotation at all levels of the cosmic mass scale from the electron to the universe;its atomic and natural units are and respectively for matter’s wave (bosonic) and particulate (fermionic) forms. The proton’s observational internal pressure Pa reported recently by Burkert et al. deviates markedly from the theoretical value ~1022 Pa, the difference attributes to challenges with existing energy measurement procedures. Velocities of electron waveform in random thermal motion evaluated with the new approach agree remarkably well with values obtained with kinetic-molecular theory KT;much more importantly, the analysis reveals existence, at standard conditions, of electron waveform’s hyper-luminal root-mean-square velocity, , if verified, this finding might inform on-going neutrino research. The evidence suggests that effects formalized in the theories of thermodynamics and kinetics trace to mobile torque fields.展开更多
