研究磁悬浮隔振器的抗饱和减振控制,针对限幅抗饱和法容易激起磁悬浮隔振器共振和Boaz Rafaely抗饱和算法的阈值很难确定,如果阈值选择过大容易激起磁悬浮隔振器共振,如果选择过小则损失减振效果这些问题,提出一种饱和约束处理方法,即加入连续惩罚函数方法。推导相应的改进LMS算法并设计出抗饱和自适应前馈控制律。通过仿真和在磁悬浮隔振器系统上进行实验对比,验证这种方法相对于限幅抗饱和算法和Boaz Rafaely抗饱和算法具有一定的优越性。
The anti-saturation damping control of the magnetic suspension isolator is studied. It is difficult to determine the resonance resistance of the magnetic suspension isolator and the Boaz Rafaely anti-saturation algorithm for the limiting anti-saturation method. If the threshold value is too large, the magnetic suspension isolator Resonance, if the choice is too small then the loss of damping effect of these issues, a saturated constraint processing method, that is, adding a continuous penalty function method. Derive the corresponding improved LMS algorithm and design an anti-saturation adaptive feedforward control law. The simulation results show that the proposed method is superior to the limiter anti-saturation algorithm and Boaz Rafaely anti-saturation algorithm.
