摘　　要：针对摆式客车倾摆控制系统的特点,采用PID控制策略,理论上分析了PID控制器的设计思想,设计了PID控制器的比例、积分、微分系数并根据其阶跃响应进行参数整定,参数整定后的PID控制系统的阶跃响应特性与仅有比例控制时相差无几,而且PID控制系统对不大于1Hz的不同频率的正弦信号的跟踪能力优良且变化不大,对于频率变化而又具有非线性特性的实测未平衡离心加速度信号的跟踪能力略有降低。仿真结果表明:直接用设计的PID控制器参数进行控制,控制效果变得更差,其参数必须经过整定;经参数整定后的PID控制系统其各种性能得到大为改善,基本满足摆式客车实际控制的要求。The PID control law is used to the tilting control system of the tilting passenger car according to the feature of the tilting system and its design is analyzed. The proportion, integrator and difference coefficient is computed and tuned based on its step response. The step response trait of the PID control system which parameters is tuned is equivalent to the proportion control system. Further, when the PID controller is used to trace the signals which frequency is less than 1Hz, its tracing ability is well. The tracing trait of the PID control system is slightly played down when the PID controller is used to trace the test signals are non- linearity and their frequency is varied. The simulated results show that the control effect is bad by the parameters of the PID controller designed directly and the parameters must be adjusted. The features of the PID controller which parameters have adjusted are largely improved and meets the real require of tilting passenger car control.
