Secondly, according to the requirement of the parametric sensitivity analysis, the method based on orthogonal experiment is chosen to cope with the difficulty of obtaining the sensitivity analysis through the partial derivative of explicit function. and it also overcomes the traditional single factor cyclical method ' s shortcoming ? impossibility to analysis interactional factors. furthermore, some significative conclusions are acquired from the sensitivity analysis
其次根據軌跡優化問題靈敏度分析的需要，選取基於正交試驗的靈敏度分析方法，解決了軌跡優化問題沒有顯函數，無法通過求其偏導數獲得靈敏度的難點，同時克服了傳統的單因素輪換法對該類問題進行靈敏度分析帶來的弊端? ?無法對有相互作用的因素進行靈敏度分析，並通過對軌跡優化問題進行靈敏度分析，得出了一些有益的結論。 -
The innovative ideas in this paper is to replace the linear fixed - gain pid controller for a nonlinear pid controller. based on the step response curves of conventional control system, we analyze the ideal variety of three gains in different times and construct the simulated curves of proportional, intergral and derivative gain. the controllers has considered all sorts of imperceptible factors affecting the servo performances in a lpmsm servo system, which include the parametric uncertainties brought by the changes of the mobile mass, the dynamitic performance of the system and the size of input. to solve the problem of so many unknown parameters, we use transmit arithmetic to find the parameters which are fit for the system. to keep the robust and stable performance
本文的創新之處在於，將傳統的固定增益的pid控制器用非線性pid控制器來代替，並在此基礎上，就一般控制系統的階躍響應曲線，分析了在不同響應時間階段pid的三個增益調節參數的理想變化情況，並根據這些理想變化，分別給出了比例、積分、微分增益參數的一種連續的非線性擬和函數。在分析雙位置環時，仔細考慮了能使系統性能變壞的各種因素，如系統的動態性能及控制出入能量的大小等等。
