High-Bandwidth Sensorless Algorithm for AC Machines Based on Square-Wave-Type Voltage Injection
TL;DR: In this paper, a square-wave-type voltage injection with signal processing was proposed to enhance the position estimation performance of a sensorless control system, and the performance of the current controller was enhanced up to 250 Hz and that of the speed controller was up to 50 Hz.

Implementation of sensorless vector control for super-high-speed PMSM of turbo-compressor
TL;DR: In this paper, two vector control schemes for a variable-speed 131-kW permanent magnet synchronous motor drive in super-high-speed applications were proposed. But the position estimation algorithm is not reliable at super-High Speed.

Analysis of algorithms for velocity estimation from discrete position versus time data
TL;DR: The least-squares velocity estimators filtered the effect of imperfect measurements best, whereas the Taylor series expansions and backward difference equation estimators respond better to velocity transients.

The measurement of instantaneous angular speed
TL;DR: In this paper, a general-purpose data acquisition system and pure software implementation are presented for the measurement of instantaneous angular speed. But, the authors do not consider the use of hardware resources without incurring additional costs in the form of upgrades to the measurement system.

A Microprocessor-Controlled Fast-Response Speed Regulator with Dual Mode Current Loop for DCM Drives
Tsutomu Ohmae,Toshihiko Matsuda,Toshitaka Suzuki,Noboru Azusawa,Kenzo Kamiyama,Tsutomu Konishi +5 more
TL;DR: In this article, a microprocessor is used to regulate the speed of a dc motor driven by antiparallel-connected three-phase dual thyristor converters, where a fast-response current controller is obtained by employing a nonlinear compensation subloop and a proportional plus integral compensation sub-loop.
