用Simulink中的SimPowersystem完成一个转速、电流双闭环直流调速系统的设计与仿真。采用三相桥式整流,平波电抗器Lp的大小可根据根据仿真调整。给出电机在空载启动,以及在2.5S后加额定负载时转速、电流、电压的变化曲线,并结合调速理论分析这些曲线。(With Simulink in SimPowersystem complete a speed, current double-loop DC speed design and simulation system. Three-phase bridge rectifier, smoothing reactors Lp size can be adjusted according to the simulation. Start the motor load is given, and the speed curve when the rated load after 2.5S, current, voltage, speed and theoretical analysis of these binding curves.)

试求的DTFT,并画出其模、相角、实部和虚部图。
实验要点:的DTFT为:,因此根据该表达式用MATLAB编程。是上取值的实变量,是复值函数,且具有周期性和对称性。图形显示时可以只考虑区间上的分布,通常还把横轴对做归一化处理。
要求:分析参考程序,写实验报告,说明编程思路。掌握有关函数abs、angle、real、imag的用法,以及有关点除运算。掌握有关绘图函数的使用。(DTFT matlab signal)
