In this paper, a nonlinear predictive controller is proposed for variable-speed induction motor. The research work directed towards improving the trajectory tracking capability, stability guarantee, robustness to parameter variations, and disturbance rejection. Generalized Predictive Control (GPC) without constraint output-constrained motor drive illustrated. variables be controlled are rotor s...

In a power system, the voltage waveform usually contains harmonics and sometimes interharmonics, often defined as components of frequency greater than fundamental component but not its integer multiple. Previous studies have reported minor effect interharmonics on cage induction machine. This paper reveals their extraordinary harmfulness for motors. Namely, may cause high vibration, which can r...

This paper presents separation harmonics to discriminate rotor failure from low frequency load torque oscillations in three phase induction motors. The most common method for detecting broken rotor bar faults is to analyze the corresponding sidebands through motor current signature analysis (MCSA). If a motor is subjected to load fluctuation, then the oscillation related sidebands exhibit simil...
