1、華中科技大學(xué)碩士學(xué)位論文永磁同步直線電機(jī)伺服控制系統(tǒng)的FPGA軟件模塊設(shè)計(jì)與實(shí)現(xiàn)姓名：韋雄波申請(qǐng)學(xué)位級(jí)別：碩士專業(yè)：機(jī)械電子工程指導(dǎo)教師：艾武2011-01-18II 華 中 科 技 大 學(xué) 碩 士 學(xué) 位 論 文 華 中 科 技 大 學(xué) 碩 士 學(xué) 位 論 文Abstract Linear motor is an new transmission that directly change energy into

2、linear motion. Because of its particular high- speed and high- precision performance, linear motor was widely used in high- speed, high precision CNC machining center .Motor controller is the core compo

3、nent of linear motor, the control performance of the controller directly affects the quality of the system. FPGA (Field- Programmable Gate Array) is a semi- custom circuit. It not only overcome

4、 the defect of system circuit, but also overcome the original limited number gates shortcoming of the programmable devices. So that, we use FPGA devices as main chip of the controller, and re

5、alize the controller’s all control functions in FPGA device. This article first analyzes the basic principles of PMSLM, and then according to the basic principles and control requirement, the ov

6、erall control framework was proposed. The overall framework was divided into four main modules. They are grating displacement and speed measurement module, closed- loop control module, coordinate transfo

7、rmation module and PWM module. Then this paper made a detail exposition of each module and its detail FPGA implement. In this paper, a new algorithm for compute promoter was proposed ,and th

8、e real- time and accuracy are greatly improved .In this paper, the classical PID control Implements the position loop, velocity loop, current loop control, SVPWM was used to control of IPM volt

9、age output. Finally, experimental verification the function of each module and verify that the controller has good control effect in actual operation. Key words: PMSLM, Servo Controller, FPGA, Fu
