Study And Implementation Of The Cable-Cabin Structural Control Method And Correlative Hardware For The Large Radio Telescope

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+plusâ…¡ 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.
