论文摘要
本文分析了基于不同电流控制开关脉冲（HC，SPWM，DPWM和SVPWM）的矢量控制方案的比较分析，以针对运动驱动的速度响应进行比较。使用不同开关技术的控制系统进行了相对模拟和分析。由于尺寸较小，性能，强大的扭矩响应以及高功率与大小比率，AC电动机驱动器逐渐用于高性能应用行业。提出了AC电动机驱动器的数学模型，以解释电动机驱动器的数值理论。矢量控制技术用于基于独立的扭矩和气隙通量控制的AC电机驱动的有效速度控制。该研究比较了每种情况下AC运动驱动器的相位电流的总谐波失真内容物和速度响应。模拟结果表明，与其他开关技术相比，SVPWM中整个相位电流的总谐波失真较小，而与其他切换方法相比，SVPWM技术的速度响应的上升时间更快。 MATLAB/SIMULINK 2018b显示了交流电动机驱动器速度控制的仿真结果。
A comparative analysis of vector control scheme based on different current control switching pulses (HC, SPWM, DPWM and SVPWM) for the speed response of motor drive is analysed in this paper. The control system using different switching techniques, are comparatively simulated and analysed. Ac motor drives are progressively used in high-performance application industries due to small size, efficient performance, robust to torque response and high power to size ratio. A mathematical model of ac motor drives is presented in order to explain the numerical theory of motor drives. The vector control technique is utilized for efficient speed control of ac motor drive based on independent torque and air gap flux control. The study compares the total harmonic distortion contents of phase currents of ac motor drive and speed response in each case. The simulation result shows that total harmonic distortion across the phase current in SVPWM is less as compared to other switching techniques while the rise time in speed response across SVPWM technique is faster as compared to other switching methods. The simulation result of ac motor drives speed control is demonstrated in Matlab/Simulink 2018b.
