Analysis and the simulation show that the time delay in semi - active system can not influence the stability of the system , but has influences on the response performances of the system . too large system time delay will enlarge the acceleration response , the ride corfortabilty will be lower , but it can not make the system unsteady 分析和仿真實(shí)驗(yàn)表明,半主動(dòng)懸掛控制系統(tǒng)的時(shí)滯不影響系統(tǒng)的穩(wěn)定性,但影響系統(tǒng)的響應(yīng)性能;過(guò)大的系統(tǒng)時(shí)滯將使系統(tǒng)的響應(yīng)加速度增大,平穩(wěn)性變差,但不致使系統(tǒng)失穩(wěn)。
