In this paper, a tank plant gearbox variable load variable speed test system electronically controlled part of the aging problem, with reference to domestic and international transmission test system design , coordination of AC and DC motor control strategy , design is more suitable for the production the process gearbox test system . The test system uses an induction motor simulation tank engine , two excited DC motor load as a simulation of the experimental system . The tank gearbox is typical gear structure induction motor control with vector control method . Take into account the mathematical model of the induction motor is a high-order , nonlinear , strong coupling of the multivariable model ; incomplete decoupling of vector control ; gearbox work in different gear control system model will change is characterized by the introduction of fuzzy control technology to improve steady-state performance of the system . According to the the different stalls governor characteristics quantization factor and the scaling factor adjustment fuzzy controller to improve the dynamic performance of the system . Vector control and fuzzy control a combination of AC and DC motor coordination control method , and this method is applied to the gearbox variable load variable speed test system design . Siemens 6SE70 inverter vector control in the design , function for asynchronous motor control , self - adjustment function of the parameters of the fuzzy controller to achieve 315-2DP PLC , through the PROFIBUS industrial bus exchange data , designed to stall control device . The test run results prove that this method is correct and feasible , to meet the requirements of the plant 's production to achieve the desired effect .
