建立了重型干式离合器同心气动离合器系统的非线性模型，并用测量数据进行了验证。开/关电磁阀用于控制进出执行器的气流。对该系统建模中的不同挑战进行了处理和讨论，以成功地推导出系统状态的适当观测器。对于需要给定系统全状态反馈的调节器应用，提出了一种基于反馈线性化的观测器，并证明了该观测器具有良好的跟踪性能。
In this paper a nonlinear model for a heavy dry clutch system with concentric pneumatic actuation is proposed and validated with measurement data. On/off solenoid valves are used for controlling the air stream in and out of the actuator. The different challenges in modeling this system are addressed and discussed to succeed in deriving an appropriate observer for the system states. For the application of a regulator, which requires a full state feedback of the given system, an observer based on feedback linearization is proposed and is shown to yield excellent tracking performance.
