Abstract


We know that the spinning machine servo system complex structure parameter is not easy to grasp the external conditions that build hydraulic servo system transfer function is difficult to accurately describe the model , these external conditions makes more difficult the transfer function design . In this paper, digital PID control and improved digital PID fuzzy PID control , making it able to receive good results in the output load control such as the spinning machine servo system with nonlinear characteristics . Spinning machine hydraulic servo system using MATLAB Simulink software module for mathematical modeling and compare simulation , so as to provide the conditions for the analysis and simulation of the proportional servo controller . The main subject of research : the first describes the current status of the spinning machine hydraulic proportional servo system . Established a the servo control mathematical model , using MATLAB software Simulink toolbox FuzzyLogic function to build the model of the input signal and the transfer function calculation , to prepare the base straight line portion of the spinning machine and spin round the rotating part of the fuzzy PID control rules . Established a mathematical model of for spinning machine servo system sports performance analysis . Secondly, digital PID control and fuzzy PID control strategy is applied to the spinning machine hydraulic servo system base position servo control with rotary servo control Simulink simulation results were analyzed using MATLAB software . The analysis of the kind of control algorithm tracking error is smaller so as to be more suitable for the control algorithm of the present system . Finally, the basic performance of the servo system of the spinning machines use AMEsim simulation analysis , analysis of the time domain and frequency domain , so have a basic understanding of the system . Added to the control algorithm , the impact on the system have a better understanding .
