摘要
在双闭环直流调速系统教学中,为使学生能够更好地理解电机起动时转速和电流的动态过程,一般采用Matlab进行仿真实验。在仿真中,速度调节器和电流调节器都采用带饱和限幅的PI调节器。速度调节器采用不同限幅方法会得到各种不同的仿真结果。本文给出了在Matlab的Simulink环境下,采用不同限幅方式时电机起动的转速和电流波形,并对结果进行了分析。
During the process of course teaching of double loop DC speed regulating system, in order to make students understand the speed and current dynamic process better during the motor starting, Matlab simulation experiment is applied. In the Matlab simulation, the speed regulator and current regulator are usually set to PI type with saturable limiter. Different simulation results can be obtained when different amplitude limiting methods are used in speed regulator. In this paper, speed and current waveforms during the motor starting are given when different amplitude limiting methods are adopted and the results are analyzed.
