摘　　要：根据汽车系统动力学原理,建立了三轴液罐车电动助力转向和主动悬架集成控制动力学模型。为了提高液罐车行驶的操纵稳定性,在MATLAB中建立PID控制的EPS控制器和模糊控制的ASS控制器,以及两者的集成控制系统,通过仿真分析不加控制、单独控制和集成控制的效果,结果表明:集成控制效果最优。According to the principle of vehicle dynamics, an integrated control dynamic model＇of electric power steering （EPS） and ac- tive suspension system （ASS） of a three axis tank truck was established. In order to improve the driving operation stability of tank truck, PID controlled EPS controller and fuzzy controlled ASS controller were established in MATLAB, and the integrated control system was built. Simula- tion analyses in MATLAB/simulink were done. The results show that the integrated control is better than no control and independent control.
