| 摘要: |
| 利用Matlab对热工自动调节控制系统和电器系统进行了仿真。总结了使用Simulink对连续时间系统动态仿真的步骤，并以典型的PID调节器DTL-331为例，利用Sinmlink模块组的Continuous，Math以及Nonlinear模块库中的模块，采用传递函数模块的方法建立系统模型．通过仿真确定了一组合适参数。另外，以电流变送器饱和仿真系统为例．介绍了如何使用PSB对电器系统进行仿真，并归纳了其仿真步骤。提出仿真过程中须注意的两个问题：构建模型时要保持系统接地点数目的平衡：正确设定电机的初值。 |

| Abstract: |
| The heat,power automatic control system and the electric appliance system are simulated with Matlab. The steps of dynamic simulation of continuous time system with Simulink are concluded. With a typical PID regulator DTL - 331 as an example,the system model is setup through the transfer functions,consisting of Continuous,Math and Nonlinear modules. A set of proper parameters is hence decided. A current transformer saturation system is taken to illu,minate the way of electric appliance system simulation using PSB,and its steps are also summed up. Two points are presented for caution:keep balance of the system grounding point number during modeling;set the initial values of motors correctly. |
