High-speedon/offvalve (HSV) has been widely concerned in the field of hydraulic engineering, mainly focusing on improving its dynamic characteristic. However, relatively little attention is paid to the adjustment of HSV switching characteristic, which limits the applications of HSVs in some specific systems. Therefore, an advanced pulsewidth modulation (PWM) control algorithm is proposed in this article to change the dynamic behaviors of the experimental HSV and makes it adjustable in a wider scope to adapt to more applications. Applying the voltages of opening preduty ratio and holding duty ratio, the opening initial current and closing initial current can be generated, respectively. Combining with the voltages of opening duty ratio and closing duty ratio, the opening and closing dynamic behaviors can be fully controlled and adjusted in a wide range. The effectiveness of the proposed algorithm is proved by numerical analysis and experimental studies. Results show that the opening delay time can be controlled in a range of 0.2–18.3 ms and the closing delay time can be adjusted in a range of 0.1–6.8 ms, while the opening moving time can be adjusted from 1.9 to 14.1 ms and the closing moving time can be adjusted from 1.8 to 6.1 ms. Consequently, the total opening time and total closing time can be controlled in the ranges of 2.1–32.1 ms and 1.9–12.9 ms, respectively. Compared with the conventional single voltage control strategy, the advance PWM control algorithm is verified to...
