摘要
弱磁调速法能量损耗小，调速平滑性高，在很多场合都得到广泛的应用，对于完全采用弱磁调速的直流电机来说，这是一种适当的解决方法。该文利用MATLAB中Simulink工具箱搭建了一个调压调速与弱磁调速配合控制的调速系统，仿真给出了该系统的动态过程和进入新的稳定状态后的各种变量曲线，其结果证明了该方法的有效性。
The method of speed regulation with field weakening is characterized with the low energy loss, higher smoothness of speed regulation, which is widely used in many occasions, and it is a suitable solution for regulating speed of DC motor by using the method of field weakening completely. In this paper, a speed regulating system is built by means of Simulink toolkit of MATLAB and coordinately controlled by the both ways of variable voltage speed control and speed adjusting with field weakening. The simulation gives the dynamic process and the various curves of variables after entering into a new stable state of the system, the simulation results prove that the way is of availability.
