摘要
提出了一种汽车主动悬架模糊控制方法,并以减小车身速度和加速度为目标,利用MATLAB/Simulink与Amesim仿真平台对混合型模糊PID控制器进行了研究。以一个受路面不平度功率谱激励下的1/4悬架模型为例,对PI控制下和混合型模糊PID控制下的主动悬架减振效果与被动悬架减振效果进行以比,结果表明,混合型模糊PID控制器能够更有效地降低车身加速度峰值,且速度峰值和加速度均方根值也有所减小,证明了混合型模糊PID控制器的可行性。
In this paper, a fuzzy control method is presented for vehicle active suspension, and a hybrid type PID fuzzy controller is studied in MATLAB/Simulink and Amesim simulation platform with the objective of reducing vehicle body speed and acceleration. This paper takes a 1/4 suspension model stimulated by road unevenness power spectrum as example to compare the damping effect of the active suspension and passive suspension under PI control and hybrid type IPD fuzzy control, which indicate that the hybrid type PID fuzzy controller is more effective in reducing peak value of vehicle body acceleration, and the speed peak value and acceleration root-mean-square value are reduced, proving the feasibility of the hybrid type PID fuzzy controller.
