Nonlinear observer and parameter estimation for electropneumatic clutch actuator
نویسندگان
چکیده
This paper proposes a nonlinear observer for an electropneumatic clutch actuator. Parameter estimation of the clutch load characteristic and friction are also treated through adaptation. Estimates of piston velocity, chamber pressures and dynamic friction state are made based on piston position measurement only. Persistence of excitation conditions for convergence of the estimation error are derived. The performance of the observer and the parameter estimation is evaluated and compared to experimental measurements.

Adaptive observer-based switched control for electropneumatic clutch actuator with position sensor
In this paper we extend previous control design applied to an electropneumatic clutch actuator. A dual-mode switched nonlinear controller design and an adaptive nonlinear observer design are combined to achieve position control of the clutch actuator with only position measurements available. The observer provides estimates of position, velocity, chamber pressures, friction state and parameters...
متن کاملEstimation of electropneumatic clutch actuator load characteristics
This paper propose a dynamic model of an electropneumatic clutch actuator system for heavy duty trucks. The focus is set on modeling of the clutch load characteristic which should be parameter affine, and the main purpose of the modeling task in this paper is to prepare for on-line adaption of this load characteristics. The knowledge of the clutch load characteristic is important for being able...
متن کاملA Robust Adaptive Observer-Based Time Varying Fault Estimation
This paper presents a new observer design methodology for a time varying actuator fault estimation. A new linear matrix inequality (LMI) design algorithm is developed to tackle the limitations (e.g. equality constraint and robustness problems) of the well known so called fast adaptive fault estimation observer (FAFE). The FAFE is capable of estimating a wide range of time-varying actuator fault...

Abstract: The paper deals with an evaluation and comparison of the estimation performance of two non-linear observers in simulation as well as in a practical application. The objectives are to underline the different parameters synthesis of both observers, the choice of the numerical solver and the difficulty to obtain good performances with an electropneumatic system. A High Gain Observer and ...
متن کاملRobust Controller Design Based on Sliding Mode Observer in The Presence of Uncertainties and Actuator Saturation
This paper studies the design of a robust output feedback controller subject to actuator saturation. For this purpose, a robust high-gain sliding mode observer is used to estimate the state variables. Moreover, the combination of Composite Nonlinear Feedback (CNF) and Integral Sliding Mode (ISM) controllers are used for robust output tracking. This controller consists of two parts, the CNF part...
