According to the technical principles of the rotational speed and current double-closed loop DC speed regulation system and pulse width modulation(PWM),the simulation modeling of the double-closed loop DC speed regulation system based on the H-type PWM reversible converter is realized by using Matlab/Simulink software.The setting of the parameters for the main simulation modules is discussed,and the corresponding rotational speed and the simulation waveform of the armature current are presented.The simulati...
直流调压调速方法简单、易控制、调速平滑性较好,并且在一定条件下可以获得较宽的调速范围,因而在直流调速系统中应用较为广泛[1-2]。而由转速调节器(automatic speed regulator,ASR)作为外环、电流调节器(automatic current regulator,ACR)作为内环组成的双闭环直流调速系统是
