基于模糊控制的废金属破碎机负荷平衡控制方法研究

摘要

为了解决废金属破碎机的负荷平衡问题,首先提出了利用模糊寻优控制解决废金属原料种类复杂的问题、利用模糊比例积分微分控制解决进料不均匀问题的基本思路;然后在此基础上,设计了模糊控制器,并研究了控制器的参数及取值;最后利用MATLAB/Simulink对控制效果进行仿真分析,并与传统比例积分微分控制效果进行了对比.仿真结果表明:采用模糊控制系统可以更有效地使破碎机负荷在安全范围内保持平衡.%Crushing and sorting scrap metal is the main way to recycle scrap metal, and scrap metal crusher is one of the most important equipment.However, problems such as the variety of waste metal materials and the un-evenness of the feed often result in the imbalance of the load of crusher, and directly affect the efficiency of crusher.Aiming at above reasons, it proposes the method of load balance control based on fuzzy control theory. Using fuzzy optimization control, it solves the complexity of raw materials of scrap metal, develops the control system and analyzes the parameters of the system, simulates the effect of fuzzy control based on MATLAB/Simu-link and compares with conventional PID control, verifies the control effect.
