About

Chuen-guey Hwang’s research centers on intelligent control systems, fuzzy logic, and pneumatic robotics, with a particular focus on cost-effective automation solutions. His most notable contributions involve the development of fuzzy PWM (Pulse Width Modulation) control strategies for pneumatic robot cylinders. In his landmark 1997 study, which has garnered 26 citations, Hwang demonstrated how to replace expensive servo valves with three inexpensive high-speed solenoid valves, achieving precise control of both linear and rotational positions. To overcome the inherent dead zone in such systems, he introduced a modified differential PWM method, significantly improving positioning accuracy. This work, alongside his earlier 1996 paper on the same topic, showcases his commitment to making advanced robotics more accessible through intelligent, low-cost hardware and fuzzy logic-based control. Hwang’s research bridges the gap between theoretical fuzzy control and practical mechatronic applications, offering a scalable approach for industries seeking affordable automation. His innovative integration of fuzzy logic with PWM control remains a valuable reference for researchers working on pneumatic systems, soft robotics, and cost-sensitive automation.
