In a companion paper (Part I), we investigated stability of induction motor drives, with resonant input filters. By using a linearized feedback model of the drive, it was shown how stability specifications could be transformed into constraints on the input admittance of the voltage source inverter. The stabilization problem then becomes a standard feedback control loop-shaping problem, where th...

Generally speed measurement is done with sensor, but disadvantage of sensor is difficult to measure speed at low speeds with sensor. These difficulties are eliminated by using sensor less Flux Orientation Controlled (FOC) . This paper proposes a Model Reference Adaptive System (MRAS) for estimation of rotor speed in FOC. An Induction motor is developed in stationary reference frame and Space Ve...

Modern AC drives require a fast digital realization of many mathematical operations concerning control and estimator’s algorithms, which are time consuming. Therefore developing of custom built digital interfaces as well as digital data processing blocks and sometimes even integration of ADC converters into single integrated circuit is necessary. Due to the fact that developing an ASIC chip is ...

In this paper presents a symmetrical five level cascaded inverter topology for Induction motor drive. It can continuously works at lower power stage. For this symmetrical circuit, when the number of level is increased, the voltage and power will also get increased. For reducing harmonics the Sinusoidal PWM method is used. The multilevel inverter gives the output to drive the three phase Inducti...

This thesis considers robust control of an induction motor drive, consisting of an input filter, a voltage source inverter and one or several induction motors in parallel. The motor torque is here controlled by using the method Indirect Self Control (ISC), and power oscillations between the inverter and the input filter are damped by means of a stabilization controller in an outer feedback loop...
