振动压路机驾驶室半主动液阻隔振系统的优化fuzzy-PID控制性能分析
Performance analysis of semi-active cab's hydraulic system of the vibratory roller using optimal fuzzy-PID control
摘要
Abstract
In order to evaluate the performance of semi-active cab's hydraulic mounts (SHM) of the off-road vibratory roller with the optimal fuzzy-PID (proportional integral derivative)control,a nonlinear dynamic model of the vehicle interacting with off-road terrains is established based on Matlab/Simulink software.The weighted root-mean-square (RMS) acceleration responses of the driver's seat heave and the cab's pitch angle are chosen as objective functions.The SHM is then optimized and analyzed via the optimal fuzzy-PID control under different operation conditions.The simulations results show that the driver's ride comfort and the cab shaking are greatly affected by the off-road terrains under various operating conditions of the vehicle,especially at the speed from 8 to 12 km/h on a very poor terrain surface of Grenville soil ground under the vehicle travelling.With SHM using the optimal fuzzy-PID control,the driver's ride comfort and the cab shaking are clearly improved under various operation conditions of the vehicle,particularly at the speed from 6 to 7 km/h of the vehicle traveling.关键词
