摘　　要：某试车台项目主要用于主减拉力轴承试验,该试验器具备施加载荷和转速的功能。试验过程中,传统的单闭环控制无法满足试验需求。为了完成试验内容,在这个项目调试中不断改进控制方式,利用PID控制器自整定计算PI参数,灵活运用单闭环控制和双闭环控制方法,并在双闭环控制的基础上增加了线性输入的改进,提升系统的动态响应特性,最终完成对系统拉力、弯矩、侧向力的控制。试验结果表明,相比于单闭环控制,双闭环控制系统的动静态性能更好,更加符合试验要求。The reform project of a test bench is mainly used for the test of main reducing tension bearing,and the test instrument is equipped with the function of applying load and speed. During the trial,the traditional single closedloop control can not meet the test requirements. In order to complete the experiment content,control mode was improved in the program debugging,self-tuning PID controller was used to calculate the PI parameters,single closedloop control and double closed-loop control method were used flexibly,and on the basis of the double closed-loop control,the improvement of linear input was added,the system dynamic response characteristics were promoted,and the control of system tension,bending moment,lateral force were completed at last. The experimental results show that compared with the single closed-loop control system,the double closed-loop control system has better dynamic and static performance,meets the test requirements more.
