Although biological systems consist of multiple mutually interacting nonlinear systems, from molecular to the social levels, they work in a fine balance and achieve functions. Recent biological studies reveal that noises play roles to manage such complex systems. Inspired by these researches, we developed a control method which can apply to a control of a complex system without modelling the control target. In this report, we propose a hierarchical control model and apply our method to the control of a human-like robotic arm.
