The invention discloses a wire harness connector welding equipment control system based on PID control. The system comprises a sensitive element sensing module and a control module which are electrically connected to an automatic welding device. The sensitive element sensing module is connected to the control module through a communication module. A PID controller is arranged in the control module. The PID controller uses a quasi-diagonal recurrent neural network to carry out multivariable PID control. PID parameters comprise a proportion, an integral and a differential which are defined in the description. The control algorithm of the PID controller (u1) is defined in the description, wherein e1 is a difference between input and output and T is sampling time. Through the above mode, the quasi-diagonal recurrent neural network (QDRNN) is used to carry out multivariable PID control parameter setting, and the PID controller adjusts the PID parameters in real time so that a welding portion is accurate and quality is good.
Description
technical field [0001] The invention relates to the technical field of wire harness connector flexible production line control, in particular to a PID control-based wire harness connector welding equipment control system. Background technique [0002] The production line process of the wire harness connector includes: cutting wire - stripping wire - arranging wire - stripping core wire - coating flux - dipping tin - automatic assembly of inner core - automatic welding - automatic assembly of shell - electrical Test—full inspection—package. Among them, welding is a related process that determines the quality and performance of the wire harness connector. [0003] Since the welding in the production process of the wire harness connection is nonlinear, and each parameter is multivariable, it will cause defects such as inaccurate welding position of the wire harness connector and poor welding quality. Contents of the invention [0004] The technical problem mainly solved by ...
