研究双位置驱动直线伺服系统动态同步控制，对解决多电机高精度同步进给和协调控制一类问题具有重要而普遍的意义。 - 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
本文的创新之处在于，将传统的固定增益的pid控制器用非线性pid控制器来代替，并在此基础上，就一般控制系统的阶跃响应曲线，分析了在不同响应时间阶段pid的三个增益调节参数的理想变化情况，并根据这些理想变化，分别给出了比例、积分、微分增益参数的一种连续的非线性拟和函数。在分析双位置环时，仔细考虑了能使系统性能变坏的各种因素，如系统的动态性能及控制出入能量的大小等等。 - The paper is the project named " theory of dynamic precision synchronization traverse and research of realization methods for linear servo dual position loops system ( no - 50075057 ) " as the background , which is supported by national natural science foundation of china drive directly by linear permanent magnet synchronous ac motor , the controlled plant eliminates middle drive parts and avoids the effects of the mechanical transmission chains from rotary motions to linear ones
本文以国家自然科学基金资助项目《直线伺服双位置环动态精密同步进给理论和实现方法研究( no 50075057 ) 》为背景，针对直线同步进给提出了一种新的控制方案：模型参考自适应控制。机床采用永磁直线同步电动机直接驱动，省掉了中间的传动环节，消除了机械传动链的影响；又因永磁直线同步电动机采用高能永磁体，具有电磁推力强度高、损耗低、电气时间常数小、响应快等特点。
