摘要
提出电控空气悬架(Electronically Controlled Air Suspension,ECAS)的参数自整定模糊PID控制策略,设计参数自整定模糊PID控制器。利用AMESim软件建立1/4电控空气悬架系统模型,采用Matlab/Simulink和AMESim在不同路面、不同车速下对空气悬架系统分别进行PID控制与参数自整定模糊PID控制策略下的联合仿真。仿真结果表明:与PID控制仿真比较,采用参数自整定模糊PID控制策略使电控空气悬架的性能指标得到显著改善。搭建1/4电控空气悬架试验台,利用电液伺服激振台进行激励加载,完成硬件在环实时仿真测试,试验结果证明采用参数自整定模糊PID控制能有效提高悬架的总体性能。
This article presents the fuzzy parameter self-tuning PID control strategy of the electronically- controlled air suspension system (ECAS) to design the fuzzy parameter self-tuning PID controller. The AMESim software is used to establish the model of 1/4 ECAS system. Under different road and speed conditions, the Matlab/simulink and AMESim are used to make the co-simulation for the air suspension system in the strategies of the PID control and the fuzzy parameter self-tuning PID control. The simulation results show that the simulation in the fuzzy parameter self-tuning PID control strategy makes the performance indexes of the ECAS significantly improved compared with the PID control simulation. A test rig of 1/4 ECAS vehicle is developed to conduct the excitation loading through the electro-hydraulic servo vibration table and the hardware-in-the-loop (HIL) real-time simulation test. The test results verify that the fuzzy parameter self-tuning PID control can improve the overall performance of the suspension system effectively.
