| 目的 螺旋式加料机构存在传感器响应时间差，造成系统延迟，非线性等问题，采用容积式来计量填充物料的质量的填充误差大。本文提出一种基于模糊PID控制的螺旋式加料机构计量控制系统。方法 利用模糊PID对螺杆式粉料加料装置进行控制，通过模糊规则对PID控制比例、积分、微分参数实现参数自调整。基于Matlab中Simulink模块下模拟该模糊PID控制系统。结果 该控制系统稳定时间减少了66%，快速性提高了21%，超调量降低了10%。结论 基于模糊PID控制系统的计量控制性能优于传统PID的。 |
| 英文摘要: |
| The screw feeding mechanism has problems such as poor sensor response time, system delay, nonlinearity, etc., and the use of volumetric methods to measure the weight of the filling material results in large filling errors. Therefore, the work aims to propose a measurement control system for a screw feeding mechanism based on fuzzy PID control. Fuzzy PID was used to control the screw powder feeding device, and fuzzy rules were adopted to control the proportion, integral, and differential parameters of PID to achieve parameter self-adjustment. The fuzzy PID control system was simulated based on the Simulink module in MATLAB. The stability time of the control system was reduced by 66%, the speed was improved by 21%, and the overshoot was reduced by 10%. The measurement control performance based on fuzzy PID control system is superior to traditional PID. |
