We advance elemental technologies through various approaches, such as control theory, measurement and analysis techniques, optimization algorithms, and signal processing, while incorporating innovations for &#8220;simplicity&#8221;.<\/p>\n\n\n\n<p>On the other hand, the research topic (2) is aimed at new developments in motion control. High-performance motion control is one of Japan&#8217;s world-leading research fields. However, since engineers involved in the control design require advanced knowledge and skills, it is hard to spread the high-performance motion control technologies in industry due to time and human cost issues. Looking to the future, the working-age population (15-64 years old) is expected to decrease to 65% of the 2010 level by 2060, making it even more important to increase productivity. To sustain and accelerate the creation of innovative technologies, we aim to create <em><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-ast-global-color-2-color\">next-generation autonomous control design technologies<\/mark><\/em> that pursue both control performance and control design efficiency by coordinately executing all design processes. We believe that the keys to the autonomous design are the cross-cutting technologies that bridge each process, and we are particularly focusing on research and development of the
