摘　　要：针对单纯改变间隙或电流难以适应磁浮列车重量变化范围大的问题,提出一种同时调节稳态间隙和电流的依从控制方法,研究了调节规律应满足的约束条件,基于线性调节规律设计了依从控制器,比较了它与定间隙控制器和定电流控制器之间的区别,并通过仿真分析不同控制方法对间隙和电流的调节效果,验证了采用依从控制器能够减小稳态间隙和电流的变化量,克服现有控制器存在的不足。Aiming at the problem that altering suspension gap or current only is hard to adapt the huge change of maglev train＇s weight, a compliance control to adjust the gap and current at the same time was provided. Then the design restrictions to compliance controller were discussed A compliance controller based on linear regularity was designed, which was compared with fixed-gap controller and fixed-current controller to study their difference. The regulative effects of the gap and current under different control methods were simulated, which validate that the compliance controller can reduce the variations of gap and current, and so overcome the shortages of existing controllers.
