TLDR
In this paper, it is shown that the flux signals may be derived from sensing coils or, with some compromise in performance, from the stator voltages and currents, and the speed signal is obtained from a digital tachometer.Abstract:
Field orientation has emerged as a powerful tool for controlling ac machines such as inverter-supplied induction motors. The dynamic performance of such a drive is comparable to that of a converterfed four quadrant dc drive. The complex functions required by filed-oriented control may be executed by microprocessors on line, thus greatly reducing the necessary control hardware. It is shown that the flux signals may be derived from sensing coils or, with some compromise in performance, from the stator voltages and currents. The speed signal is obtained from a digital tachometer. Results from a 2-kW experimental drive are given.read more

A stator flux oriented induction machine drive
TL;DR: In this article, the sensitivity of a rotor-flux-oriented system using rotor flux estimation is discussed, and a stator-fluency-oriented scheme is developed, where the estimation of the stator flux is independent of the leakage, and the steady-state performance is insensitive to the leakage inductance.

Microcomputer control of high dynamic performance ac-drives--a survey
TL;DR: It is shown that by combining a suitable machine model with the principle of rotor- or field-orientation a unifying basis for the design of ac-drives is created and the complicated signal structure of the control systems can be handled by microelectronics, i.e. by using software instead of elaborate hardware.

Control of induction motors via feedback linearization with input-output decoupling
TL;DR: In this article, a linear decoupling of rotor speed and rotor flux is proposed to achieve both high dynamic performance and maximum power efficiency in an induction motor by employing a parameter adaptation method.
