Research on Advanced Control Strategies of Induction Motor System
The induction motor (IM) is a nonlinear, uncertain, and complex controlled object that is difficult to drive and control. When the system parameters change or has external disturbance signal, the system cannot return to the original state of equilibrium, to which active disturbance rejection control (ADRC) has been shown to be an effective solution. ADRC regards the external disturbance and str...
متن کاملStator Current Harmonic Assessment of Induction Motor for Fault Diagnosis
This paper presents an assessment of motor current signature analysis for fault diagnosis of an induction motor. Single phasing fault has been considered and stator current harmonics are analyzed by assessing peaks and symmetry in harmonic spectrums both at normal condition and at fault condition. ‘db4’ is used for current signature analysis wavelet decomposition. A comparative observation is m...
متن کاملTorque Improvement by Third Harmonic Current Injection into Multi-phase Machines with High Saturation
One advantage of multi-phase machines is the possibility to use the third harmonic of the rotor flux for additional torque generation. This effect can be maximized for Permanent Magnet Synchronous Machines (PMSM) with a high third harmonic content in the magnet flux. This paper discusses the effects of third harmonic current injection (THCI) on a five-phase PMSM with a conventional magnet shape...
متن کاملLearning Control of Current-fed Induction Motor with Mechanical Uncertainties
In this paper repetitive learning control technique has been applied to the position/flux tracking control of an Induction Motor (IM) under hypothesis of periodic reference trajectory and uncertainties on the mechanical model. The electro-magnetic IM model has been directly taken into account in the control development. Indirect Field Oriented approach has been exploited and combined with contr...
متن کاملAn improved current injection network for three-phase high-power-factor rectifiers that apply the third harmonic current injection
A novel current injection network for low-harmonic rectifiers that apply the third harmonic current injection is proposed in this letter. The current injection network requires one inductor, two capacitors, and one 1 : 1 transformer with voltampere rating of only 0.16% of the input power. The transformer is introduced to provide complete rejection of harmonic components of the injected currents...
