Qu, Ming-fei; Zhao, Dan

In order to improve the anti-interference control ability of vacuum packaging machine, the design method of anti-interference control system of vacuum packaging machine based on wireless network is put forward. The system design is divided into anti-interference control algorithm design and hardware design of vacuum packaging machine. The parameter distribution model of anti-interference control of vacuum packaging machine is constructed. The output voltage, power and potential field of vacuum packaging machine are taken as the control constraint parameters. The difference between the output phase current of the vacuum packaging machine is calculated, the saturation function is constructed to analyze the control decision variables of the vacuum packaging machine, the sampling output voltage stabilizing characteristic quantity and PWM duty cycle are taken as the modulation parameters, the equivalent mechanical power and equivalent electromagnetic power of the vacuum packaging machine are calculated, and the network output design of the anti-interference control system of the vacuum packaging machine is carried out in the wireless network. The hardware design of anti-interference control system of vacuum packaging machine is carried out by using FPGA. The test results show that the output stability of anti-interference control of vacuum packaging machine is good and the robustness of motor control is strong.
