摘要
为了适应高性能高可靠性直线传动伺服系统的要求,设计一种双余度电动作动器。主要包括:2台新型的同步磁阻永磁(SR-PM)电机,2套智能功率模块逆变电路,2套数字信号处理器的控制电路和2套直线位移传感器系统。系统采用了位置闭环下的矢量控制和双余度控制策略。在此基础上,对系统进行了动态响应实验和故障切换实验,其中阶跃位置响应和正弦位置响应实验均实现了快速位置跟踪,保证了实验在故障发生时刻迅速实现电机运行模式的切换。实验结果表明:系统能够保证快速的动态响应和较高的可靠性,能够适应高性能传动控制系统的要求。
A double redundancy electrical-mechanical actuator was designed for high-performance and high reliable linear drive servo system. This electrical-mechanical actuator contains two synchronous reluctance with permanent magnet （SR-PM） motors and drive systems, two inverters with intelligent power module （IPM）, two control circuit systems with high-performance digital signal processor （DSP） and two linear position sensor systems. Position feedback-based vector control and double redundancy control strategies achieve high reliability and fast response. Dynamic response experiment and error-switching experiments show that the system quickly tracks the reference position in dynamic experiments with both a step reference position and a sinusoidally varying reference position. The system can switch the running mode within the error time in the error switching experiment. Thus the system achieves fast dynamic response and high reliability in high-performance electrical drive systems.
