About

Tatsuaki Yokoyama is a pioneering researcher in robotics and control systems, best known for his foundational work on the Virtual Internal Model Following Control System (VIMFC). His key research areas include robotic servo control, trajectory tracking, and advanced control architectures for manipulators operating in working coordinate systems. Yokoyama’s major contribution lies in proposing an alternative control framework that enhances the precision and robustness of robot arm movements by integrating internal models into the servo loop. This innovation addresses critical challenges in trajectory tracking, enabling more accurate and adaptive responses to external disturbances. Although his most cited paper, “Virtual Internal Model Following Control System” (1988), has accumulated 15 citations, its influence extends beyond raw numbers, as it introduced a conceptual shift in how robotic systems can be designed for real-world applications. Yokoyama’s work has been particularly impactful in the development of industrial and service robots, where reliable motion control is essential. His research continues to inspire engineers and researchers exploring model-based control strategies, making him a respected figure in the robotics community for his early and enduring contributions to the field.
