Sensorless five-phase induction motor drive with third harmonic injection and inverter output filter [PDF]
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2020 The paper presents a sensorless control approach for a five-phase induction motor drive with third harmonic injection and inverter output filter. In the case of the third harmonic injection being utilised in the control, the physical machine has to be ...

Convergence and adiabatic elimination for a driven dissipative quantum harmonic oscillator [PDF]
, 2015 We prove that a harmonic oscillator driven by Lindblad dynamics where the typical drive and loss channels are two-photon processes instead of single-photon ones, converges to a protected subspace spanned by two coherent states of opposite amplitude.

Compound optimal control of harmonic drive considering hysteresis characteristic [PDF]
Mechanical Sciences, 2019 Hysteresis behavior widely exists in the transmission process of harmonic drives. Eliminating the hysteresis effect is highly desired in the high-precision mechanical transmission, which results in challenges in the control design.
