| This PaPer investigates fuzzy control of wood milling Proeessing on-line control system according to fuzzy control theory.Firstly I had checked the international and local literature about wood milling, fuzzy control and siinulation with coumPuter, thenI Put fuzzy intellective control to the wood milling Proeessing system in order to increase the accuracy of the wood Proeessing and increase economic income:Next,I had analyzed the function characteristic of the wood Proeessing system,then educed system model of simPlification.The wood Proeessing on-line control system is a comPlicated system, it is difficult to establish its accurate mathematics model, being aPPlieable to fuzzy control, and summed uP exPerience data about the wood milling Proeessing system according to foregone exPerimental data: Then, designed the fuzzy controller of this system, the fuzzy control system is the a single inPort-single exPort system, its imPort variable is the error between the measured and Perfect surface roughness, its exPort variable is controlled variable-voltage u, we can regulate the rotate speed of the eleetrieal engineering according to u, then educe the speed of the workbench, and gained ideal surface roughness.the fuzzy logical controller is designed with tow dimension structure, making sure the membershiP function value of imPort and exPort variables and fuzzy control rules according to expert's experience, and calculating the system fuzzy control table off-line.Simulated the wood milling Proeessing fuzzy control system made use of engineering software MATLAB adoPtion command line, the S function and FIS GUI separated based on the designed fuzzy controller, and educed the dynamic simulated carve, from the carve we educed the fuzzy controll system had smaller system characteristic, shorter rise time and quicker stabilizing time ete. |
