Other AbstractAs the digitized and intelligentized tendency of AC servo system is concerned, this dissertation carries out an in-depth anaysis and research for a control system, which is based on AC servo wheel executing agency and consists of high resolution angle measuring instrument-photoelectricity encoder. Now, AC servo system is used broadly because of its high performance. In allusion to the requirements of the project, we have selected Panasonic AC servo system. A large scale programmed chip-FPGA is adopted to design a control block that is a communication bridge between the master computer and the servo system. Furthermore, we have designed a pure hardware subdivision scheme to dispose the signal of the feedback encoder to improve the resolution and meet real time requirement of the closed loop. The result indicates that the peak value of subdivision errors is 0.25" .At last, we have set up a hardware structure using an 1-dimension rotary table. At the same time, a control software with advanced PID arithmetic has been successfully designed and applicated after being debugged for many times. Location precision is up to 0.28" (RMS), and velocity stability is improved from 3% to 0.5%. In a word, the dissertation contains some important experience for the farther exploitation and application of AC servo system.
