“…As mentioned earlier in the literature descriptions [ 24 , 47 , 49 , 50 , 51 , 52 , 53 , 69 , 70 ], the actuator coil is modeled as a normal coil with an air gap. The attempts to change to a version with a moving component inside the coil [ 54 , 55 , 56 , 58 ] are also based on the relations that describe a normal coil with an air gap.…”

The article presents a model-based evaluation of the impact of the plunger stroke on functional parameters of the low-pressure pulse gas solenoid injector. A reduced-order physics-based mathematical model was used to achieve this goal. The model was built on the basis of specified simplifications of the process, considering the forces that cause the plunger to move and the forces constituting resistance to its displacement. The implementation of a mathematical description in to the Matlab-Simulink environment allowed one to determine the characteristic values of operation of the Valtek Rail Type-30 injector, including plunger displacement courses. Calculations made with the assumption of the factory plunger stroke confirmed the validity of the model. The differences in opening and closing times were below 3% in comparison to the values given in the objects technical information. By assuming a specific plunger stroke, the functional relationships of opening and closing times were determined. The results showed a distortion of the force–response dependence for different plunger strokes. Results presented in the article can be used to support control-oriented modeling of systems incorporating pulsed gas dosing devices, such as combustion engines or gas turbines. More specifically, the proposed method can be used to pre-calibrate the delay time of the injector operation.

“…A large part of the mathematical model describing the operation of an electromagnetic circuit with a coil is based on an air coil without a movable core [ 49 , 50 , 51 , 52 , 53 ]. If it already tries to take into consideration the movable core, it is converted to an air coil in the end anyhow [ 54 , 55 , 56 , 57 , 58 ].…”

“…Miller J I designed a new pneumatic valve to improve the response of air-actuated brakes for heavy vehicles to demand pressures generated during electronically controlled braking [21]. P X Li et al used a double voltage driving circuit to reduce the switching time and delay time of the highspeed on/off valve, and hence, the response characteristics and the control performance were optimized [22,23]. Lee designed and manufactured an electronic valve driving circuit with fast response characteristics by using a three-power source.…”

Based on the classification of automated driving by the SAE (Society of Automotive Engineers) and the working principle of the ECPBS (Electronically Controlled Pneumatic Brake system), the requirements and the control modes of the APRV (Automatic Pressure Regulating Valve) were concluded. Four structural configurations for APRV were proposed to meet the requirements of the ECPBS. To study the pressure regulating characteristics of the APRV of different structure configurations, a simulation model was established, and a test bench was built. Through experiments, the correctness and the reliability of the simulation model were verified. The pressure regulation characteristics of the APRV of different structure configurations under different control conditions were revealed, and the suitable levels in the SAE automated driving classifications for automatic pressure regulators of different structure configurations were determined; thus, the theoretical underpinning to improve driving safety and develop automated driving was provided.

“…At present, there are many studies focused on improving the dynamic characteristics of the HSV by optimizing the driving strategy. Li et al [9] proposed a double voltage driving strategy to a generate larger driving current and smaller maintenance current, which effectively improved the response characteristics of the HSV. On this basis, multivoltage source circuits [10,11] have been studied, which can shorten the closing time of the HSV by generating reverse voltage.…”

Analysis of Dynamic Characteristics and Power Losses of High Speed on/off Valve with Pre-Existing Control Algorithm

et al. 2021

A high-speed on/off valve (HSV) is generally the core component of a digital hydraulic transmission system. Therefore, its dynamic characteristics often restrict the overall performance of the digital hydraulic system. Most of the current studies focus on the optimization on the dynamic characteristics or the energy characteristics, few studies have comprehensively considered the two characteristics of the valve together. In this paper, a pre-existing control algorithm (PECA) is proposed to improve the dynamic characteristics of the HSV, and simultaneously optimize the power losses of the HSV to improve its energy conversion efficiency. The results show that, compared with the traditional single-voltage driven strategy, the opening time of the PECA decreases by 29.4%, the closing time decreases by 59.6%, and the energy conversion rate increases by 7.9%.
