Abstract:The mechanism of speed instability involving belt conveyor directly starting is analyzed, that the dynamic torque needed for additional acceleration is the main reason for starting instability is pointed out. By applying the hydro-viscous soft starting device to the starting of belt conveyor is able to ensure starting stability. According to the working principle of soft starting device, through the local linear processing, the mathematical model of soft starting device is built, and its transfer function is solved. Aiming at the perturbations and uncertainty of system parameters, a method of fuzzy PID controller is designed. The stability of the speed regulation system is ensured by using the self-tuning function. The simulink toolbox of Matlab is used to conduct the simulation experiment. The results show when the system transfer function changes, the fuzzy PID has a better adaptive capacity, faster response, better robustness, and is able to assure that the system obtains good speed regulation characteristics.
