摘要

针对基于力矩电机的旋转直驱阀难以满足燃油系统高精度要求的问题，设计了一种基于两相混合式步进电机的直驱阀位置电流双闭环控制策略，以提高控制效果，该策略具有高阶超扭转观测器（HOSTO）抗扰能力强和基于积分的快速终端滑模（IFTSM）速度快的优点。对电机转角和阀流量进行了仿真。结果表明，所提出的IFTSM-HOSTO能显著消除传统滑模控制中的抖振现象。该旋转直驱阀在8 MPa进口压力和标准输出压力的工况下，在0.08 s内实现快速稳定，在瞬态过程中实现零超调。

Study on flow control strategy of a fuel valve directly-driven by two-phase hybrid stepper motor

Due to the difficulty in meeting high precision requirements of fuel system with a rotary direct-drive valve based on a torque motor, a position and current dual closed loop control strategy of direct-drive valve using a two-phase hybrid stepper motor is designed to improve the control effects, which has the advantages of strong disturbance resistance of High-order Super-twisting Observer (HOSTO) and rapidity of the Integral-based Fast Terminal Sliding Mode (IFTSM). Simulations are conducted on rotation angle of the motor and flow rate of the valve. Results show that the proposed IFTSM-HOSTO can significantly eliminate the chattering phenomena in traditional sliding mode control. The rotary direct-drive valve demonstrates rapid stabilization within 0.08 s under operational conditions of 8 MPa inlet pressure and standard delivery pressure, achieving zero overshoot during the transient process.

期刊介绍： Flow Measurement and Instrumentation is dedicated to disseminating the latest research results on all aspects of flow measurement, in both closed conduits and open channels. The design of flow measurement systems involves a wide variety of multidisciplinary activities including modelling the flow sensor, the fluid flow and the sensor/fluid interactions through the use of computation techniques; the development of advanced transducer systems and their associated signal processing and the laboratory and field assessment of the overall system under ideal and disturbed conditions. FMI is the essential forum for critical information exchange, and contributions are particularly encouraged in the following areas of interest: Modelling: the application of mathematical and computational modelling to the interaction of fluid dynamics with flowmeters, including flowmeter behaviour, improved flowmeter design and installation problems. Application of CAD/CAE techniques to flowmeter modelling are eligible. Design and development: the detailed design of the flowmeter head and/or signal processing aspects of novel flowmeters. Emphasis is given to papers identifying new sensor configurations, multisensor flow measurement systems, non-intrusive flow metering techniques and the application of microelectronic techniques in smart or intelligent systems. Calibration techniques: including descriptions of new or existing calibration facilities and techniques, calibration data from different flowmeter types, and calibration intercomparison data from different laboratories. Installation effect data: dealing with the effects of non-ideal flow conditions on flowmeters. Papers combining a theoretical understanding of flowmeter behaviour with experimental work are particularly welcome.
