基于FPGA直流电机PWM的控制实现

浙江大学硕士学位论文AbstractAbstractIn this paper,DC motor as the study,with the application of FPGA-advancedtechnology,designs an all-digital stepper motor control system,through variousprogram text links of the simulation,synthesis and downloads,and gets a goodapplication in experiments.This paper analyzes the DC motor works,as well as its specific control process,describes the FPGA design principles and the related chips those are involved,thengives a brief introduction on the knowledge of applied hardware language VHDLall these provides a theoretical basis for the specific design sections of the paper.The system against the achievement of the DC motor speed control,designs acontinuously adjustable pulse signal generator that can meet the requirements andmodular programmings for the whole system,each sub-module has pasted thesimulation tests.The system uses a modular design concept.It's not only convenientfor the system design and maintenance,but also improve the performance of thesystem scalability.The system adopts software hardening ideas,applies the VHDLhardware language which is easy to be understood.The software is also adopt severalswhich are used widely at present.FPGA VHDL EDA tools constitute the field of digital system integrationtechnology,as a core part of the system design,the skill with operationalflexibility ,cheap and widely use.This kind of technology has strong vitality and broadprospects,and will further the development of system integration of the entire ICindustry.The whole system uses a fully digital control scheme,making the systemmore compact,more rational and economical.Because the system's all digital,theoperation of the whole system become very reliable,the debugging is convenient,too.As an advanced technology,the paper makes many new attempts in several sapects.Key Words:DC motor,Field programmable gate array,VHDL
