| 摘 要： | 以单磁铁悬浮系统为研究对象,运用自抗扰控制技术,设计两种非线性悬浮控制算法,给出一些参数整定规律。仿真结果表明,非线性PID算法和模型补偿自抗扰算法都具有快速、无超调和无静差的优点,但后者对系统内外的大扰动和模型的不确定性表现出更强的鲁棒性和适应性。

| Abstract: | Based on active-disturbance-rejection control technology,two nonlinear algorithms are designed for single electromagnet levitation system.Subsequently,several regulations for parameters' tuning are presented.The simulation results demonstrate that both NLPID and model-compensation ADRC have advantages of quick response,no overshoot,and no steady-state error,of which the latter has stronger robustness and adaptability as to massive disturbance of system and model uncertainty. |
