【摘要】 本文在全面深入了解大射电望远镜FAST光机电一体化创新设计方案的设计思想和技术指标的基础上，结合50米模型的工程实践，重点研究了两个问题：1．提出了基于非线性跟踪微分器的插值模糊控制算法(TDIFLC)，讨论其在大射电望远镜悬索馈源定位外环控制系统中的应用；2．应用FPGA／CPLD技术完成悬索馈源定位系统中外环控制系统的基于ISA总线的联动伺服控制卡的设计与实现。具体内容包括： 针对悬索馈源系统为—非线性、时变、大滞后、多变量耦合系统，精确的数学模型难以建立，采用经典控制理论与现代控制理论进行系统的分析和设计比较困难，甚至无法获得比较理想的运行效果。因此本文采用了一种具有高控制精度的模糊控制算法—基于非线性跟踪微分器的插值模糊控制算法(TDIFLC)，对其控制策略进行研究，并以悬索馈源外环控制系统为控制对象，对其进行分析和数值仿真，其结果证明了此种控制算法的可行性和高效性，并且结构简单，易于工程实现。 为了实现悬索馈源系统的精确定位，应用FPGA／CPLD技术设计和实现了联动伺服控制卡。采用了数字系统的自顶向下的设计方法，选用了Altera FPGA系列器件和MAX+plusⅡ软件设计平台。在文中，给出了设计和实现的方法，并且通过软件仿真和试验验证，其结果满足精度要求，而且具有较高的可靠性，比较简洁的结构，更具有功能可扩展的灵活性。更多还原

【Abstract】 Based on the in-depth understanding of backgrounds and requirements for the opto-mechatronics design for the Large Radio Telescope, combined the engineering practicalities of 50m model, this dissertation studies two problems: 1.It presents an Interpolation Fuzzy Control Algorithm based on Nonlinear Tracking Differentiator (TDIFLC), and discusses it’s application on the Cable-Cabin attitude control system for the Large Radio Telescope. 2.Design and implementation of the Cooperative Working Servo Motor Control Card for the Cable-Cabin attitude control system for the Large Radio Telescope using the FPGA/CPLD technology. The detail can be seen blow:To counter the characteristics of the Cable-Cabin attitude control system, nonlinear, structure time-variable, large delay and control modeling difficulty, it is difficult to analyze and design the system by the classical control theory or the modern control theory. We can not obtain a perfect control precision. So this dissertation puts forward an improved fuzzy control algorithm that has higher controlling precision-an Interpolation Fuzzy Control Algorithm based on Nonlinear Tracking Differentiator (TDIFLC). This dissertation gives its design methods. Simulation results show the effectiveness and efficiency of the proposed controller. And the improved algorithm is simple and easily to be implemented.In order to realize location with a high precision I select the FPGA/CPLD technology for design and implementation of the Cooperative Working Servo Motor Control Card. Adopt an up-down method for the digital system, using Altera FPGA series and MAX+plusⅡ software. Here the method of design and implementation are presented. Through simulation with software and verification with experimentation the result satisfies the accuracy. It has a higher reliability and has a briefer structure; even it has the flexibility of expansion.更多还原
