Based On Embedded Systems Research For BLDCM

With the development of the computer,communications,electronics,detect,machinery and NC, and other related technologies, control technology is also rapidly developing and has become the indispensable foundation technology in modern manufacturing systems. For Brushless DC motor control requirements, will help improve the control precision and is beneficial for system for complex process of the realization, and is conducive to achieving flexibility, accuracy, reliability, and a pleasant nature, and other functions to provide important guidance and reference value.This paper mainly aimed at the exclusive control of the BLDCM system based on embedded environment, introduced two ARM-based DSP and embedded operation mode, building its experimental circuit hardware and software environment and realizing controlling the BLDCM. In the overall there are two design points.The first part is in the ARM environment, and first in the embedded Linux systems, introduced the background and development of Linux experimental, using MagicARM2410 build the cross-ARM Linux compiler environment, cut the core to product and achieve the needed on-chip SOC Shifting values, using vivi editor to programming, arm-gcc compile the process, for the exclusive control of several software systems. This was followed by theμC/OS-II real-time operating system, analysis in which environment code generation tools and the use of integrated development environment of ADS software, and the use of debugger and the AXD command simulator software, and the H-JATG achievement of hardware simulation. Once again is in the Win CE environment, introduced the system of basic Win CE operating environment, achieved cutting the core system in the software Pb environment, completed the core transplantation, the connection of host and objectives of the establishment and in the software eve to achieve control procedures in the preparation, compile, download.The second part is in the DSP environment, realized the hardware target board TMS320F2812-A + software development environment CCS2.0 + debugger ICETEK5100USB simulation of the control framework, introduced the experiment hardware development board features, software and the use of simulation debugger, Construction of the final control under the framework of the hardware circuit.In order to test the feasibility and scientific system in the whole, the author brings out s suit of experiment equipment. First of all, is based on the ARM system, experimental me onboard motor control has provided us with great convenience, after a number of experiment, the motor is achieved positive and reversal and the governor reached a satisfied results. This was followed by the DSP-based system, built the framework of the entire hardware system after setting up the control structures, from simulation to the real circuit, realized the special requirements for BLDCM control. In papers presented at the last ARM and DSP system as a whole on the test results.
