直线电机复合分层抗干扰控制方法研究

Research on compound layered anti-disturbance control method of linear motor

针对直线电机运作过程中不同类型干扰对电机的影响,提出了一种复合分层控制方法。将电机运行过程中受到的干扰分为两类:第一类是周期性干扰,第二类是范数有界干扰。分别设计了全阶干扰观测器和H∞控制,将两者结合起来形成复合控制。在dSPACE半实物仿真平台中,对策略进行了实验验证。实验结果表明,复合分层控制方法将干扰分为不同的类型,采用不同的方法来应对,与传统方法将所有干扰视为是一种类型相比有着更好的抗扰效果。

Aiming at the influence of different types of disturbance on the motor during the operation of the linear motor,a composite layered control method is proposed.The disturbance received during the operation of the motor is divided into two types:the first type is periodic disturbance,and the second type is norm-bounded disturbance.The full-order disturbance observer and H∞control are designed separately,and the two are combined to form a compound control.In the dSPACE hardware-in-the-loop simulation platform,the strategy was verified by experiments.The experimental results show that the composite hierarchical control method divides the disturbance into different types and adopts different methods to deal with it.Compared with the traditional method,which treats all the disturbance as one type,it has a better anti-disturbance effect.
