摘　　要：为改善某特种车辆在崎岖路面行驶时的平顺性,分别以车身质心的垂向运动、俯仰运动与侧倾运动设计了悬架自抗扰控制器。使用MATLAB/Simulink模块化地搭建七自由度整车模型,以D级路面与凸块路面作为输入进行系统仿真。结果表明:设计的控制器能有效改善车辆在恶劣路面行驶时的平顺性,保证了车身姿态平稳,控制效果明显优于PID控制器与被动悬架。In order to improve the ride comfort of a special vehicle running on rough roads,an active disturbance rejection controller(ADRC)of the suspension was designed based on the vertical,pitch,and roll motion of the vehicle body’s centroid.A seven-degree-of-freedom model of the whole vehicle was built by using MATLAB/Simulink.D-level and convex pavements were used as input to complete the system simulation.The results show that the designed controller can effectively improve the ride comfort of the vehicle running on harsh roads and stabilize the body attitude.In addition,its control ef‐fect is obviously better than PID control and passive suspension.
