摘要
基于分数微积分理论,提出分数阶"天棚"阻尼控制概念,并以它控制的悬架为参考模型,提出一个控制效果理想、鲁棒性好的悬架滑模控制的新策略,并应用于非线性悬架的动力学控制中.文中给出了一种精度较高,收敛稳定的分数阶系统的数值算法,最后对非线性悬架的滑模主动控制进行数值仿真,验证了新控制策略优良的控制效果.
The concept of fractional order skyhook damping control was presented based on fractional calculus theory. Taking a suspension model controlled by the new skyhook damping as the reference model, a new excellent sliding mode control strategy for suspension systems was proposed and applied in the control of a nonlinear suspension. A kind of numerical scheme for fractional order system with high accuracy and stability was also given. The new sliding mode control for an active suspension with nonlinearities was investigated through numerical simulation. The computational results verify the good control efficacy of the new strategy.
