摘要
在分析了传统伺服系统设计的基础上,提出了伺服系统结构/控制一体化设计方法,建立了含齿隙非线性的伺服系统模型,给出了包含结构参数和控制参数的优化模型,以系统的齿隙为目标函数,采用遗传算法对机械结构参数和控制参数进行了一体化设计;仿真结果表明:在满足系统跟踪精度要求的前提下,系统的齿隙增加了8.15%和14.5%,降低了齿轮的加工精度;齿轮箱的占用空间减少了3.05%,满足系统要求。
Based on the analysis of a conventional servo system design issues. The method of Integrated Structure and Control Optimization to the servo system has been presented, based on the model of pitch- ing part with the nonlinearity of backlash Further more, the optimum model including structure and con- trol parameters has been proposed with the dimension of backlash as the objective function to optimize the structure and control parameters. Simulation results shows that the dimensions of backlash are augmented by 8. 15% and 14.5 % ,reducing the machining precision, and the space using by the gearbox is reduced by 3.05% ,which accords with the requirement of space to servo system, based on the request of the tracking precision has been met.
