基于DSP的多联空调机组控制

Control System of Multi-connected Air Condition Unit Based on DSP

多联空调机组控制系统是将变频模块、变频压缩机和制冷系统有机集成一体的控制单元,其技术核心是变频控制模块。结合矢量脉宽控制技术、智能功率模块和数字信号处理器件,实现一个基于DSP和IPM(智能功率模块)的矢量控制变频调速系统。文中对系统的工作原理、硬件和软件进行了分析研究。测试结果表明,系统具有良好的动、静态性能。

The control system of multi-connected air-condition unit is the control unit which combines a variable frequency module, a variable frequency motor of compressor and a system of refrigeration. Its technical core is the variable frequency control module. The paper realized a variable frequency and adjusting speed system controlled by vector based DSP and IPM. The operation principle, hardware and software of the system are analyzed and studied. The testing results proved that it had good dynamic and static performance.
