Abstract

Permanent Magnet Synchronous Motors having the advantages like composite structure, high torque and high efficiency, find wide application in different engineering fields. Evaluation of the characteristics of the motor helps in analysing the dynamics of the machine. Real-time simulation platforms play vital role in emulating complex systems when actual system is not available. Various performance characteristics of the machine evaluated with MATLAB under different operating conditions are validated with the help of real-time simulator HIL 402 in this work.

Abstract

Permanent Magnet Synchronous Motors (PMSM) are considered as energy efficient motors suitable for modern applications like electric vehicles. Field oriented control or vector control is a superior control strategy for PMSM drives. It is known that in vector control, decoupled control of torque and flux is obtained as in the case of a DC motor. The objective of this paper is to compare and analyze the performance of a vector controlled Permanent Magnet Synchronous Motor which uses Sinusoidal PWM and space vector PWM techniques. Sinusoidal PWM and Space vector PWM are pulse width modulation techniques used for controlling the three phase inverter which drives the motor. They have the advantage of decreased harmonic content in the generated output voltage. Space vector modulation has the added advantage of increased DC bus utilization. Here both the methods are implemented along with FOC to control the PM motor and the results are analyzed. Simulation is carried out in MATLAB Simulink platform and the results are compared.

Abstract

Regenerative braking can be used in electric vehicles as a process for recycling the brake energy, which is impossible in the conventional internal combustion vehicles. PI control is a popular method in electric car control, but it is difficult to obtain correct brake current. By combining fuzzy management and proportional integral control ways, regenerative braking force will distribute the mechanical braking force and electrical braking force. Braking force is mainly effected by many factors and three most important factors: SOC, speed, and brake strength are taken as the fuzzy control input variables. Regenerative Braking System (RBS) can obtain brake current, which is used to produce brake torque. PI control have adopted to adjust the BLDC motor PWM duty to obtain the constant brake torque. PI control is quicker than fuzzy control, that two methods combined together can realize sleek transitions. The performance of the proposed system has been analyzed through simulation using MATLAB-SIMULINK. [ABSTRACT FROM AUTHOR]

Abstract

The acoustic noise emitted by an induction motor, powered by a voltage source inverter, is an environmental issue. Harmonics present in the stator current are the main reason for the increased acoustic noise in motor drives. The pulse-width modulation technique used to modulate the inverter is the key factor determining the magnitude of current harmonics. Bus-clamping pulse-width modulation (BCPWM) techniques have got much attention nowadays due to reduced switching loss, compared to conventional space vector pwm(CSVPWM). In this paper, two BCPWM techniques namely, 60° and 30° BCPWM methods are compared with CSVPWM on the basis of electrical spectra as well as acoustic noise spectra. Experiments are conducted on a pulse-width modulated voltage source inverter fed 6 kW induction motor drive. Harmonic analysis is carried out on the measured line to line voltage, stator current and acoustic noise, corresponding to the three methods, at different fundamental and carrier frequencies. Comparison of the experimental results show that the magnitude of dominant acoustic noise component around the carrier frequency is reduced significantly with BCPWM methods, compared to CSVPWM, at high modulation indices.

Abstract

This paper presents an experimental procedure to determine the acoustic and vibration behavior of an inverter-fed induction motor based on measurements of the current spectrum, acoustic noise spectrum, overall noise in dB, and overall A-weighted noise in dBA. Measurements are carried out on space-vector modulated 8-hp and 3-hp induction motor drives over a range of carrier frequencies at different modulation frequencies. The experimental data help to distinguish between regions of high and low acoustic noise levels. The measurements also bring out the impact of carrier frequency on the acoustic noise. The sensitivity of the overall noise to carrier frequency is indicative of the relative dominance of the high-frequency electromagnetic noise over mechanical and aerodynamic components of noise. Based on the measured current and acoustic noise spectra, the ratio of dynamic deflection on the stator surface to the product of fundamental and harmonic current amplitudes is obtained at each operating point. The variation of this ratio of deflection to current product with carrier frequency indicates the resonant frequency clearly and also gives a measure of the amplification of vibration at frequencies close to the resonant frequency. This ratio is useful to predict the magnitude of acoustic noise corresponding to significant time-harmonic currents flowing in the stator winding. [ABSTRACT FROM PUBLISHER]
