Induction machine models used for steady-state and transient analysis require machine parameters that are usually considered design parameters or data. The knowledge of induction machine parameters is very important for Indirect Field Oriented Control (IFOC). A mismatched set of parameters will degrade the response of speed and torque control. This paper presents an improvement approach on roto...

The influence of the rotor time constant mismatch on the global stability of induction motors under indirect field oriented control (IFOC) is analyzed. A test for global stability is provided, based on necessary and sufficient conditions for the existence of quadratic Lyapunov functions for IFOC drives. This test yields robustness margins with respect to rotor time constant mismatches. A typica...

In this paper, the position control of a detuned indirect field oriented control (IFOC) induction motor servo drive is studied. A PID-fuzzy logic position controller (PID-FLPC) is designed and analyzed to achieve high-dynamic performance both in the position command tracking and load regulation characteristics for robotic applications. The performance of the proposed PID-fuzzy logic and synchro...

This paper presents a comparison between Sensor or Indirect Field Oriented Control (IFOC) and Sensor-less Field Oriented Control (SFOC) in low frequency region for Induction Motor (IM). These two strategies can be considered among the family of Vector Control (VC) methods and provide a solution for high-performance drives. Most of the Electrically-operated Overhead Travelling (EOT) Crane IMs ar...

This paper presents the performance of the extended Kalman filter (EKF) for speed sensorless indirect field oriented control (IFOC) of a squirrel cage induction motor (IM) supplied by a pulse width modulated (PWM) voltage-source inverter. The rotor speed of the induction motor is estimated, according to this method, using the direct measurements of the stator voltages and currents without the s...

It is well-known that the system performance for an indirect fieldoriented control (IFOC) induction motor drive degrades under parameter variations and in the presence of external load torque. In this paper, a novel plug-in robust compensator for position control enhancement of an indirect field-oriented induction machine drive is developed. This plug-in compensator, designed using the H∞ loop ...

In the recent days, for traction and electric vehicle (EV) applications, multiphase machines with pole phase modulation (PPM) technique have been proposed. The smoother operation during changeovers as well steady-state operations is a significant constraint while adopting PPM-based induction motor (PPMIM) drives EV applications. So, in this paper, PPMIM dynamic model associated vector control a...

Induction motors (IMs) have widely been regarded as one of the most suitable options in automotive industry for electric propulsion systems of hybrid electric vehicles (HEVs) due to their reliability, ruggedness and low cost. In the past, poor dynamic response of IMs was a key constraint that limited their capability in applications that require speed tracking and fast positioning. However, the...
