基于PLC的钢管定长切割模糊智能控制系统研究

针对现有飞锯定长精度低和传统PID控制策略存在的不足,提出利用PLC技术结合模糊PID算法的智能控制策略,实现PID控制参数的在线自适应调整。通过MATLAB仿真软件,进行了常规PID控制与模糊PID控制动态性能的仿真比较,研究结果表明采用模糊PID控制可明显提高其动态响应性能及定长切割的精度。

Steel Pipe's Fixed-length Cutting Control System Based on Fuzzy Intelligent and PLC

Aiming at the weak points of low precision on fixedlength cutting and the traditional PID control strategy on flying saw machine, proposes a control strategy based on PLC and the fuzzy PID intelligent method,realizes the online adaptive control of PID control parameters.The fuzzy PID control is compared with traditional PID by simulation through MATLAB.The results indicate that the steel pipe＇s fixedlength cutting dynamic control performs and cutting precision much better by us ing the fuzzy PID control strategy.
