| 英文摘要 | Transmission test bench is the test equipment that tests the quality of the transmission. Using transmission test bench to test the performance of the transmission before leaving factory can check whether the transmission has the quality problems in the processing and assembling. That can ensure the transmission quality. The control system as the core of the transmission test bench, its performance will directly affect the test performance of the transmission test bench and the test results. Research on the transmission test bench control system has some important significance for improving control precision of the transmission test bench, improving test performance, ensuring reliability of the test results and so on. This paper relies on the ShenYang HuaChen Power Machinery Co., Ltd’s transmission assembly line project, research and design the transmission test bench control system. The control system structure adopts electric closed structure based on common dc bus that has simple structure, high power utilization, stability and some other advantages. I propose that use genetic algorithms to optimize PID controller parameters used in the control system that simplifies the commission process of PID tuning and ensures the accuracy and stability of the control system.

Study the vector control theory of the induction motor, and build the transmission test bench loading control system model, and provide a theoretical support for the transmission load control system torque and speed PI controller design and MATALAB simulation model build of the loading control system. Research the PID tuning based on the genetic algorithms, and program the MATLAB program of the PID tuning based on the genetic algorithms, and design the torque and speed PI controller of the transmission loading control system. Then design the transmission test bench control system according to the general design requirements of the transmission test bench control system. And select the key hardware components of the control system, and build the network of the transmission test bench control system based on PROFINET. And analyze and design the communications between PLC and SINAMICS S120. According to the functional requirements and work principle of the transmission test bench, design and develop the PLC control program and WinCC monitoring program. Finally, build the MATLAB simulation model of the loading control system of the transmission test bench. and use genetic algorithms to optimize the torque and speed PI controller parameters, and use the MATLAB simulation model to simulate loading test of the transmission. And according to the tuning parameter of the speed PI controller to set the actual speed PI controller parameters of the loading control system on the transmission test bench control system speed control loop, and do the corresponding transmission loading tests. The speed control performance is good, comparing with the simulation results, the both speed trends are consistent. The transmission test bench control system that is designed in this paper meets the requirements of the transmission performance test, the system is stable and reliable. |
