Based on the Nios II PWM DC Motor Control System
Design
Abstract
Along with the development of electronic technology, microprocessor technology,
signal detection and processing technology, automatic control theory and computer
application technology and permanent magnet materials technology, people have
made a great progress on the movement control system. Thus speeding up the DC
motor the speed governing and servo systems evolving into the integrative motor and
the control digital direction of proceedings, for the Motion Control System of high
real-time, strong stability of the control requirements, provides a guarantee and basis.
In accordance with Motion Control System for the high real-time, strong stability of
the control requirements, development of high precision and high efficiency and open
the Motion Controller of great significance.
In this thesis, two-phase DC motor to control the object, to use the Nios II-based
Avalon peripherals customized technology, to use large-capacity single-chip field
programmable gate array(FPGA)as the core controller, design based on programmable
chip system (SOPC, System on Programmable Chip) technology of motion controller.
At first, this thesis introduces the electric transmission system and the basic situation
of PWM technology, illustrates the technology of control system, which is designed in
this paper. Secondly, the thesis introduces the method of building a true small-scale
SoC(System on a Chip)for DC motor control system with embedded soft-core FPGA
internal Nios II and illustrates ideas and the way to the realization of SOPC. This
system uses a common DC motor PWM speed control program and the FPGA chip
named EP2C35F672C6 on ALTERA's DE2 development board as the system
controller. At the same time, it integrates some circuit which is needed by speed
control to DC motor control system with the help of hardware description language.
Thus it provides a new way of the motor control. Finally, this paper provides several
key functions in the control system software to explain how to control the movement
of motor.
Based on the above design, I’ve made a solid model and carried out proof tests, the
related results proved the feasibility and correctness of this design. The program of the
SOPC system technology which are composed of Nios II soft-core in this thesis have
many advantages and characteristics, such as highly integration, high flexibility,
scalability and can greatly shorten the product development cycle.
