为了保证高速磁浮列车沿轨道方向安全、可靠的运行,针对其导向控制系统建立了双电磁铁导向系统动态模型,设计了以电压、电流为受控对象的四种闭环控制器,并利用MATLAB/SIMULINK软件分析了各控制器的稳态性能和抗干扰能力。仿真结果表明:电流作为控制对象具有对非线性导向系统更好的模拟性,引入加速度反馈有利于改善系统的抗干扰性能,PID控制器设计方案具有相对更优的控制性能。
In order to ensure the safe and reliable operation of the high-speed maglev train along the track direction, a dynamic model of the dual electromagnet guidance system is established for its guidance control system. Four kinds of closed-loop controllers with voltage and current as controlled objects are designed. SIMULINK software analyzes the steady-state performance of each controller and anti-interference ability. The simulation results show that the current as the control object has a better simulation of the nonlinear guidance system, and the introduction of acceleration feedback is conducive to improving the anti-jamming performance of the system. The PID controller design has relatively better control performance.
