Actual Engaged Gear Identification: a Hybrid Observer Approach
نویسندگان
چکیده
The knowledge of the actual engaged gear is essential to achieve highquality control of an automotive power train. In cars equipped with manual gear shift, this information is not directly available. A hybrid observer for on–line identification of the actual engaged gear is proposed. Two hybrid models of an automotive driveline, a detailed one for verification and a reduced-order one for synthesis, have been developed. The identification algorithm is based on a novel approach to observer design for hybrid systems. The algorithm was tested on experimental data obtained at Magneti Marelli Powertrain on an Opel Astra equipped with a Diesel engine and a robotized gearbox and yielded excellent results.

Dynamic Sliding Mode Control of Nonlinear Systems Using Neural Networks
Dynamic sliding mode control (DSMC) of nonlinear systems using neural networks is proposed. In DSMC the chattering is removed due to the integrator which is placed before the input control signal of the plant. However, in DSMC the augmented system is one dimension bigger than the actual system i.e. the states number of augmented system is more than the actual system and then to control of such ...
متن کاملDesign of nonlinear parity approach to fault detection and identification based on Takagi-Sugeno fuzzy model and unknown input observer in nonlinear systems
In this study, a novel fault detection scheme is developed for a class of nonlinear system in the presence of sensor noise. A nonlinear Takagi-Sugeno fuzzy model is implemented to create multiple models. While the T-S fuzzy model is used for only the nonlinear distribution matrix of the fault and measurement signals, a larger category of nonlinear systems is considered. Next, a mapping to decou...
متن کاملMode Identification for Hybrid Model of SI Engine to Detect Misfire Fault
Identification of operating mode is a key step in the fault diagnosis of the hybrid systems. The novelty of this paper is the definition of a hybrid observer where discrete event is identified and then continuous model of a sub-system is selected for the design of observer using sliding mode technique. The observer output is finally used for mode identification and fault diagnosis. The proposed...

متن کاملAn LPV Approach to Sensor Fault Diagnosis of Robotic Arm
One of the major challenges in robotic arms is to diagnosis sensor fault. To address this challenge, this paper presents an LPV approach. Initially, the dynamics of a two-link manipulator is modelled with a polytopic linear parameter varying structure and then by using a descriptor system approach and a robust design of a suitable unknown input observer by means of pole placement method along w...
