谁能帮我翻译一下，谢谢了！

Vehicles with automated manual transmissions (AMT) for gear shift control offer many advantages in terms of reduction of fuel consumption and improvement of driving comfort and shifting quality. Complexity, nonlinearity and high-order dynamics of the automated driveline, Combined with strict requirements for high performance gear shifts, demand the development of driveline models, which include a detailed description of the actuators. These models can be useful for different purposes: (a) during system development, to evaluate the achievable performance and its dependency on system properties; (b) as simulation tools for gear shift control algorithm design. In this paper, physically-based detailed nonlinear models of the electro-hydraulic actuated gearbox and of the dry clutch electro-hydraulic actuator of an automated manual transmission are developed. In order to analyze their behavior and their impact on the drive train during gear shifts. Actuator models are integrated with a simplified transmission shafts dynamics. A reduced-order model of the gearbox actuator, which is valid when dither signal is imposed to servo-valves, is developed with the aim of analyzing g its properties and performances.
Model parameter identification has been performed mostly by means of theoretical relations and design data. Experimental tests, performed on a commercial car, confirm that the proposed model is able to describe the actuators behavior and the main phenomena characterizing system dynamics during gear shift.
Automatic transmission control represents one of the key elements for the improvement of vehicle safety, comfort, reliability and driving performances together with the reduction of fuel consumption and emissions in modern vehicles [1]. Different approaches, such as automatic, continuously variable and automated manual transmission, have been pursued [2,3,4]. The AMT, exploiting the availability of reliable drive-by-wire technologies, represents an important solution for the automotive industry and is spreading in the last years, mostly in the European car market.
An AMT is generally constituted by a dry clutch and a multi-speed gearbox, both equipped with electro-mechanical or electro-hydraulic actuated system, which is the most frequent solution thanks to its lower weight and the possibility of integrating the actuators with existing hydraulic equipments. The operating modes of AMT s are usually two: semiautomatic, with the driver requesting a sequential gear shift by means of a proper interface, or fully automatic. In both cases, after the gear shift request, the ECU takes the control of the sifting strategy, by issuing suitable command signals to the engine, the dry clutch ad the gearbox, according to current engine regime, driving conditions and driving mode, e.g. economical or sport profile.
