本文介绍了无刷直流电机的工作原理，研究了无刷直流电机的PWM调制方式，实现了基于Nios软核的无刷直流电机控制系统的SOPC设计。系统硬件包括以FPGA为核心的控制电路和用于电机驱动的三相全桥逆变电路，对FPGA及其外围设备的选择和逆变电路的设计做了大量研究工作。软件设计包括在Quartusn中用vHDL语言生成的位置检测模块、电机控制模块和PID调节器的IP核以及在 SOPCBullder中实现NioSH软核和外围IP核的定制和控制软件的设计。重点对PID调节器的FPGA实现做了一些探讨。
本文针对逆变电路的工作方式，运用PWM调制技术，做了全桥调制和半桥调制实验，并对实验结果进行了分析。实验表明，本无刷直流电机控制系统运行性能良好，调试方便，开关噪音小，升级换代容易，为后续的研究工作提供了基础和借鉴。(June 2009 based on the NIOSII the brushless DC motor controller design the Zhuang Renqin Dalian Maritime University Thesis power electronics and electric drive)

Radar-on-FPGA
主要论述了基于FPGA的末制导雷达伺服系统设计。结合末制导雷达讨论其电机控制、二阶伺服系统性能和PID校正算法,利用VHDL语言设计,实现基于FPGA的方位步进电机开环定位控制和俯仰直流电机闭环速度控制的伺服系统。结合实际应用中遇到的问题,提出了基于"反馈控制"理论的有效的补偿算法,该算法提高了伺服系统的稳定性、快速性和精度。(Mainly discusses the design of terminal guidance radar servo system based on Field Programmable Gates Array(FPGA).It includes the system’s electric machine control,second-order servo system performance and PID correction algorithm based on Virtual Hardware Description Language(VHDL) on azimuth stepping motor open loop positioning control and pitch direct current electric machine closed loop speed control of the FPGA servo system.In allusion to some factual problems during its application,presents corresponding effective solutions based on traditional control theory "Feedback Control".The fact proves that these methods can greatly improve the stability,speediness and precision of the original servo system.Additionally,a basic algorithm which can be realized in a terminal guidance radar servo system is given)
