【摘要】：變速箱加載試驗臺是變速箱下線檢測的關鍵設備,試驗臺電控系統是試驗臺完成試驗任務的重要基礎,一直是試驗臺開發(fā)領域的重要課題之一,隨著試驗臺性能的提升,對其電控系統提出了更高的要求,電控系統的好壞將直接決定試驗臺研制是否成功。依托于某新能源汽車試驗臺,結合國內外研究成果并根據客戶要求搭建一套變速箱試驗臺電控系統,并以其為研究對象,設計了系統組成、控制結構和控制策略。針對生產線快節(jié)奏的要求通過全自動輥道將試驗臺同生產線對接,將試驗臺納入裝配線體系中,在試驗臺系統內部,通過輥道將各工位串聯起來,提高了系統的自動化率與生產效率。通過直流電機與異步電機數學模型對比了兩種驅動加載方式的優(yōu)缺點,然后推導了異步電機在定子坐標系下的電磁轉矩模型,分析了電壓空間矢量對電磁轉矩的影響,給出一種DTC控制結構,提高了動態(tài)加載精度。對傳統的直流母線結構進行了優(yōu)化使系統更加緊湊,采用獨立整流器布置并進行了響應與負載分析,分析了工作狀態(tài)中直流母線的變化特性,計算了系統反饋率,經測試直流母線反饋率達到65%。采用交叉耦合控制方法,建立傳動系統理想動力學模型,針對轉動慣量不同、負載擾動的問題提出控制輪間轉速差的控制策略,然后借鑒"主—從控制"的優(yōu)點提出了一種改進的反向交叉耦合控制方法解決了差速器兩端轉速不匹配的問題,設計了模糊PID控制器實現了控制參數的自整定,提高了系統對環(huán)境的適應性。最后對文中反向交叉耦合控制方法進行測試,測試了系統的同步性與追隨性,試驗效果達到了設計要求,現已隨新能源汽車變速箱試驗臺一同交付業(yè)主使用,并已通過了現場驗收證明了本套系統設計的可行性,相較該企業(yè)老式試驗臺,提高了設備性能,為企業(yè)節(jié)省了成本,創(chuàng)造了良好效益。
[Abstract]:The gearbox loading test bench is the key equipment for detecting the gearbox downline. The test bench electronic control system is the important foundation for the test bench to complete the test task, and has been one of the important topics in the field of development of the test bed. With the improvement of the performance of the test bed, A higher demand is put forward for the electronic control system, which will directly determine the success of the development of the test rig. Based on a new energy vehicle test bench, combined with the domestic and foreign research results and according to customer requirements to build a set of transmission test stand electronic control system, and take it as the research object, designed the system composition, control structure and control strategy. In order to meet the requirement of fast rhythm of the production line, the test bed is connected with the production line through the automatic roller table, and the test bed is brought into the assembly line system. In the test bed system, the stations are connected in series through the roller table. The automation rate and production efficiency of the system are improved. The advantages and disadvantages of the two driving modes are compared by the mathematical models of DC motor and asynchronous motor. Then the electromagnetic torque model of induction motor in stator coordinate system is derived, and the influence of voltage space vector on electromagnetic torque is analyzed. A DTC control structure is presented to improve the dynamic loading accuracy. The traditional DC bus structure is optimized to make the system more compact. The independent rectifier is arranged and the response and load are analyzed. The variation characteristics of DC bus in the working state are analyzed and the feedback rate of the system is calculated. The feedback rate of DC bus is 65. An ideal dynamic model of transmission system is established by using cross-coupling control method. A control strategy is proposed to control the rotational speed difference between wheels for the problems of different moment of inertia and disturbance of load. Based on the advantages of master-slave control, an improved reverse cross-coupling control method is proposed to solve the mismatch between the two ends of the differential speed. A fuzzy pid controller is designed to realize the self-tuning of the control parameters. The adaptability of the system to the environment is improved. Finally, the reverse cross coupling control method is tested, and the synchronization and tracking of the system are tested. The test results meet the design requirements, and have been delivered to the owner with the new energy vehicle gearbox test bench. The feasibility of the system design has been proved by field acceptance. Compared with the old test bed, the equipment performance has been improved and the cost saved and good benefit created for the enterprise.
