随着直流无刷电机应用领域的不断扩大,对控制系统的稳定性和实时性提出了更高的要求.以DSP芯片ADMCF340为控制核心,设计了永磁无刷直流电机的控制系统,并给出了部分硬件电路图和控制软件流程图.该系统利用DSP芯片的快速运算功能和面向电机控制的专用外围设备,实现了电流、速度的全数字双闭环控制.研究结果表明,该系统稳定可靠,实时性良好,为永磁无刷直流电机的广泛应用提供了一定的理论参考依据和工程实际方法.%In order to solve the problems of high risk operation, low control precision, long time feedback regulation and poor system scalability caused by the single complex control, a double-core joint-control circuit for inverted power supply system is designed and realized in this paper, which is based on the joint control of microprocessor STM32F103 with ARM7 Cor-tex-M3 Core and TI C2000 series DSP chip TMS320F2808. It uses STM32 for system management, environmental monitoring and human-machine interaction, and F2808 for close-loop feedback control and battery charging. Both the modularization of digital control, and facilitation of operation and maintenance were realized by the control system. The controlling and loading experiments indicate that the new control scheme has effectively solved the problems mentioned above. The test results show the feasibility and vendibility of this kind of inverted power supply system.
