摘要
针对适合在小空间运行的新型双臂翻板门的负载特性,设计基于ARM控制的直流无刷电机控制系统.采用磁场定向控制算法控制直流无刷电机的电机定子相电流,使之接近于正弦波,使得电机运行平稳、响应快,提升机构的运行动态性能.负载自学习的功能提高门运行的安全,CAN通信模式实现模块化硬件控制结构,使得系统运行可靠性高、易于维护.
Aiming at automatic performance and space requirements of an automaticflap door with complex load property,a controlling system based on ARM micro-processor control unit is designed.In this control system, thefield-oriented control algorithm for the magneticfield of BLDC improves the rigid output performance and dynamic characteristics of the motor with sine wave phase current.The ability of learning mechanical property intelligently enhances the reliability of the system.The CAN communication method is applied to the modular hardware units.All the features make the running of the motor more stable,and the response faster and easier to maintain and upgrade.
