Implement Of R600Linac Motor Unit Position And Velocity Feedback Control

In order to meet the clinical needs of cancer treatment more, improve product competitiveness, achieve positioning real-time verification of the tumor therapy, currently The topic can improve the linear accelerator, add a linear accelerator to R600EPID System. The topic provides practical realization of motion control program for the EPID system. The topic achieves position and velocity feedback control, provide improved programs for motor control of other linear accelerator. In addition, as a separate component,EPID can be used not only The R600linear accelerator of Neusoft and future high energy linear accelerator, but also can be used for other manufacturers to improve the accelerator without EPID, therefore, the application of EPID S ystem prospects.The topic n-depth study on the control panel of the motion control system of EPID system, including the design program of system control panel, chip select, the specific realization of the main circuit module. This thesis not only designs the hardware platform of the system control panel, but also using C language achieves algorithm on DSP development tool software. The thesis using VHDL language finishes the logic control module on CPLD development tools. Ultimately the thesis achieve a completely system control panel. The following of the main contents:(1) A brief explanation of the development of the linear accelerator, a analysis of its development, and the significance of the key component of EPID motion control system.(2) The analysis of the overall structure of the motion control system, the performance requirements and the overall program of control system software and hardware. Focused on the function and the basic form of the system, the details of the working principle of the system, and the structure and function of each component.(3) A more comprehensive description of the hardware implementation of each module of the electronic control system. Focused on the division of hardware modules and hardware design, the details of the circuit diagram of each hardware module.(4) A depiction software implement of the motion control system, a introduction CCS software features, composition and function, Using the C language configure the hardware modules, and the describes of the development and design process of CPLD design, the describes motion control algorithm of the servo motor.(5) The analysis of the important device of the motion control panel., the selection of the important chip of the main control panel, the integration of each module. This thesis achieves the original intention of the design.
