摘    要:电流环是磁浮列车悬浮控制器的重要子系统。在分析PI型电流环及最速电流环的控制特点的基础上,设计了一种次速电流环控制器,它具有调节速度快、抗信号扰动能力强、对对象参数不敏感等优点。仿真表明次速电流环的调节速度和最速电流环相当,但在系统中存在干扰信号时,抖动会明显减小。实验表明,次速电流环调试方便,能结合悬浮控制子系统很好地完成悬浮任务。

关 键 词:磁浮列车  悬浮控制  PI型电流环  最速电流环  次速电流环

Abstract:The current-loop is a key subsystem of the magnetic levitation controller on maglev vehicle.Based on the analysis of controlling features of PI and time-optimal current-loop,the paper presents a design of hypo-time-optimal current-loop control system,which has the advantages of fast adjustment,strong anti-disturbance and insensitiveness to system's parameter.Simulation results show that the hypo-time-optimal current loop was as fast as the time-optimal current-loop and had less vibration when noise interfuses into the system.The experiment results indicate that the hypo-time-optimal current-loop can be regulated conveniently,and can also be successfully applied in magnetic levitation control system.
Keywords:maglev vehicle  levitation control  PI current-loop  time-optimal current-loop  hypo-time-optimal current-loop
