Analysis of Voltage Distortion and Comparison of Two Simple Voltage Compensation Methods for Sensorless Control of Induction Motor

Popis výsledku v původním jazyce

Many algorithms of induction motor sensorless control need accurate knowledge of the stator voltage vector. However, the machine is in most cases supplied by a two-level voltage-source inverter; therefore, the voltage is distorted by the inserted dead-time and also by nonlinearities of the semiconductor switches. This paper analyzes a distortion caused by the dead-time and delayed IGBT switching in terms of distorting voltage vector. An offline measurement is performed to obtain the inverter model. Then, an analysis of two simple volt-seconds-based compensation methods (compensation of the reference voltage vector and duty cycle, respectively) on the accuracy of the speed estimation of a sensorless field-oriented control based on the rotor flux model reference adaptive system is performed. The analyzed methods use either the full inverter model implemented as a look-up table or its trapezoidal approximation. Outline on computational complexity and discussion on finding optimal coefficients for the trapezoidal model are given, too.
