HTF58X2注塑机螺杆筒温度的模糊PID控制
Fuzzy-PID control of the screw barrel temperature of a HTF58X2 injection molding machine
摘要
Abstract
The characteristics and requirements of a HTF58X2 injection molding machine's screw barrel temperature control system were analyzed.Considering that traditional PID controllers' screw barrel temperature control system is difficult to obtain the satisfactory temperature control because of its features of non-linearity, pure lag and time variation, an adaptive controller using the online adjustment of PID parameters based on the fuzzy strategy was proposed.The controller can realize the on-line adjustment of its parameters by fuzzy reasoning according to the iste input temperature deviation and the variance rate of the deviation to adapt itself to the best matching of PID parameters under different working conditions.The results of the Matlab/Simulink simulation and experiment show that the fuzzy-PID controller has certain advantages in the aspects of adjusting speed, overshoot and adaptive ability in comparison with the fixed parameter PID controller.关键词
