摘　　要：针对轮毂电机驱动的车辆非线性主动悬架,基于区间二型模糊理论提出了一种混合事件触发的控制方法。首先,为准确地捕捉该悬架系统非线性和参数不确定性,建立了区间二型Takagi-Sugeno模糊模型;其次,为有效地缓解网络带宽负荷,引入了一种包含时间和事件触发机制的混合事件触发策略,且两种触发机制之间的切换满足伯努利分布;而后在时滞理论的基础上,构建了非线性悬架的闭环系统模型,并设计了一种混合触发的模糊控制方法。最后,通过仿真验证了上述方法在提升乘坐舒适性和资源节约性方面优于现有方法。A hybrid-triggered control method based on interval type-2 fuzzy theory was proposed for in-wheel motor-driven vehicle nonlinear active suspension.Firstly,the interval type-2 Takagi-Sugeno fuzzy model was established to accurately capture the nonlinear and parametric uncertainty of the suspension system.Secondly,in order to alleviate the pressure of network bandwidth effectively,a hybrid-triggered strategy was introduced,which included both time and event triggering mechanisms,with the switching between the two triggering mechanisms following a Bernoulli distribution.Thirdly,based on the theory of time delay,the closed-loop system model of the nonlinear suspension was constructed,and a hybrid-triggered fuzzy control method was designed.Finally,the simulation results show that the proposed method is superior to existing methods in improving ride comfort and saving resources.
