Simulation Research for the Double Loop DC Speed Control System of Multi Rope Friction Hoist

为保证设计的提升机直流调速控制系统的可靠性,对设计的直流调速控制系统进行仿真研究,仿真方式是基于SIMULINK中动态结构框图的仿真,仿真步骤是按照控制系统先内环后外环的原则,首先对电流内环进行仿真,并根据一定的近似条件,将电流内环从双闭环中独立出来,然后配置数据进行仿真,从仿真结果中观察提升机控制系统的跟随性。对双闭环直流调速模型的仿真是在电流内环的基础上进行的,用来观察提升机直流传动系统的起动过程中检验提升机系统的整体性能指标,包括动态性能指标和抗扰性能指标。

In order to guarantee the reliability design of hoist DC speed control system, the simulation research of the DC speed control system design was done, emulation mode was the simulation of dynamic structure diagram based on the SIMULINK, simulation process was under the principle of control system inner ring first outer ring after, carries on the simulation of the inner current loop, and according to the approximate conditions,the inner current loop will be separated from the double closed loop,and then configurated data for simulation, observed following performance of elevate machine control system from the simulation results. The simulation of double closed loop DC speed control model was based on the current loop,which used to observe the overall performance index system inspection enhance the starting process of the DC transmission system of the machine, including dynamic performance and anti-disturbance performance index.
