摘　　要：在ISS(input-to-state stability)框架下设计闭锁离合器闭锁压力观测器。考虑到了建模误差和外部扰动,引进ISS理论来调节估计器参数,保证系统稳定,其中模型的不确定性作为扰动输入,估计器的设计保证了误差系统是ISS稳定的。基于AMESim建立了自动变速器传动模型,将设计好的观测器在MATLAB/Simulink中实现并与AMESim传动模型进行联合仿真,以验证设计的闭锁离合器闭锁压力观测器的正确性,并与已有的滑模观测器进行了比较,有较好的表现。The lock-up clutch pressure observer is designed based on input-to-state stability（ ISS）.Considering the modeling error and additional disturbance,the ISS theory is introduced to theory to adjust the estimator parameter and ensure the system stability,and taking the uncertainty of model as disturbance inputs and the estimator is designed to ensure the error system is input- to- state stable.Based on the AMESim,the transmission model of automatic transmission is established.The designed observer is realized in the MATLAB/Simulink,and the joint simulation with the transmission model is carried out to verify the correctness of designed lock- up pressure observer of lock- up clutch.Comparing with the sliding mode observer,the designed pressure observer has the better performance.
