About

Petrus Sutyasadi is a robotics and control systems researcher whose work focuses on making advanced robotic platforms—from quadruped robots to articulated arms—more stable, precise, and accessible. His major contributions center on developing robust control algorithms that handle real-world uncertainties, such as unmodeled dynamics and external disturbances, while remaining simple enough to implement on low-cost embedded systems like Arduino. Sutyasadi’s most cited paper (2020, 18 citations) proposes a particle swarm optimization-based H₂/H∞ robust controller for robotic arm joints, directly addressing the cost barriers of Industry 4.0 migration. He has also pioneered gait tracking and push recovery control for quadruped robots, using differential evolution and mixed-sensitivity H∞ methods to ensure stable trotting even under side impacts (14 and 7 citations, respectively). His work on PID-ILC trotting control (11 citations) further demonstrates his commitment to practical, implementable solutions. Notably, Sutyasadi extends his expertise to sustainable applications, as seen in his recent IoT-enabled solar panel cleaning robot (2025). By consistently bridging advanced control theory with frugal hardware, his research empowers vocational education and small-scale industries to adopt sophisticated automation.
