摘要
研究传动装置问题,电磁齿轮通过安装在轴承上的一对通电线圈产生的磁场来传递动力。输出负载的变化需通过调整输入电流的大小来实时整定。为了能够实时根据负载变化快速调整输入电流的大小以适应输出的变化,为使传动力稳定,不受噪声干扰,利用建立电磁齿轮传动的动力学模型,在构建以电流为输入、总阻转矩为输出的传递函数,采用电磁齿轮传动系统的零极点配置自校正控制算法,设计了相应的控制器,并在MATLAB的Simulink环境下进行了动态仿真。仿真结果表明,系统能够根据负载的变化实时地调整相应输入,对干扰和参数变化的适应性,保证了系统运动控制的快速性、准确性和稳定性,使电磁齿轮控制系统取得了较好的综合控制性能。
Electromagnetic gears are used to transfer power through magnetic field produced by the electrical coils installed on bearing.The input current may be used to drive the change of the output loads by adjusting on time.For adjusting the input to adapting the load change,this paper has set up the dynamic model of the electromagnetic gears and deduced the transfer function with the electric current as input and the torque as output.According to the principle of the electromagnetic gears transmission system,a pole and zero placement self-tuning control algorithm was designed.At last,dynamic simulation was given.The result shows that the control system of electromagnetic gears transmission can adjust the input electric current according to the load change in real-time.It makes the control system rapid,accurate and stable,and improvea the dynamic behavior obviously.
