—The induction motor squirrel cage that is deemed by its strength, high torque mass, and its relatively low cost ... etc, meanwhile, it benefited from the support of industry since its invention. Despite these advantages, the induction motor has complex dynamic systems that exhibit a strong nonlinearity, which makes them difficult to be controlled. The use of control algorithms is therefore des...

This paper describes an Intelligent Bio-inspired optimization technique to minimize the square of errors in the parameters of an induction motor. The torque ripples and speed error would degrade the performance of the machine. In order to enhance the performance parameters of cage rotor type induction motor, the speed error and torque ripples should be minimized. This can be achieved by tuning ...

Abstract: Induction motors are the dominant components in industrial processes involving electromechanical energy conversion. Safety, reliability and efficiency are major concerns in modern induction motor applications. Since detecting faults on time could avoid costly unscheduled shutdowns, in recent years there has been an increased interest in induction motor fault detection and diagnosis. I...

This paper presents an alternative input/output modelling of a squirrel-cage induction motor drive system. Usually these systems are modelled using state variables like rotor currents or linking fluxes, some of them extremely difficult to obtain. A neural network based learning through examples algorithm is used to represent the motor dynamics, using only input/output information. This is very ...

A modified approach, involving the addition of a low frequency boost voltage, is developed and adopted as an enhancement to the conventional closed loop f v speed control of a three-phase squirrel cage induction motor modeled in the stationary qd reference frame using six-step voltage source inverter waveform. The results obtained show a superior performance in the two basic mechanical characte...

The paper presents a synthesis of an extended Gopinath observer (EGO) and analyzes the asymptotic stability of a squirrel-cage induction motor vector control system with an EGO in its loop. The considered control system is based on the direct rotor flux orientation method (DFOC) and the study of stability is based upon the linearization theorem applied around the equilibrium points of the contr...

This paper analysis the variables needed to represent the internal dynamics of a squirrel-cage induction motor drive system. This is an important issue when automatic input/output modelling, based on learning through examples algorithms, is considered. These modelling techniques allow a precise knowledge of the drive dynamics, fundamental topic in modern control approaches, without using variab...

the paper presents the methodology for obtaining the level of noise in three-phase induction motors with squirrel cage rotor. Investigations include a single-speed motor with 3000 r/min and a two-speed motor with 750 and 1500 r/min. The investigated motors (manufactured by a Romanian company) were placed in a semi-anechoic chamber in order to determine the noise-to-frequency characteristics (sp...

This study investigates the simple vector control of a 3-phase squirrel cage Induction Motor (IM) under open-circuit fault (faulty 3-phase IM). It was shown that it is needed to supply the stator windings with unbalanced currents to remove the oscillating term of the machine electromagnetic torque. The vector control system is based upon Field-Oriented Control (FOC) that has been adapted for th...

This technology was developed by to reduce the cost of supplying electricity in remote communities. The optimal wind penetration (installed wind capacity/peak electrical demand) for this system depends on the sit...
