Abstract(in English) Because reinforcement learning (RL) methods have an advantage such that a control rule can be obtained autonomously without any knowledge of the target system. RL methods have been successfully applied to automatic control of various robots such as balancing control of a cart-pole. However, most real control problems have non-linear dynamics with a large number of degrees of freedom, therefore it is necessary to develop an RL method to deal with such situations. This difficulty is called "curse of dimensionality" in the context of RL. We formarly proposed an RL method that switches controllers which had been developed in the field of control theory, and applied our method to an automatic control problem of an acrobot. The results showed that a good controller for a simulator can be obtained autonomously but the control of the real acrobot was not stable. In the current study, we propose an RL method which is robust against the system identification error, and show that a good controller for a real robot can be obtained by our method.
