【摘要】 在设计一个控制系统之前对系统进行仿真是很有必要的。本文介绍了采用SVPWM调制的矢量控制系统的原理,并在Matlab/Simulink环境下建立了系统的仿真模型,给出了仿真结果,并与采用电流滞环PWM调制的矢量控制系统的仿真结果进行对比,结果显示SVPWM在减小电磁转矩脉动方面具有明显的优势。更多还原

【Abstract】 The vector control system with SVPWM is introduced in the paper,and a system model is established for simulation in Matlab/Simulink.A comparison with the traditional PWM system is also giwen.As a result,SVPWM has a great advantage in decreasing the fluctuation of torque.更多还原
