Abstract

In this chapter, a cutoff-frequency phase-in method to deal with the problem of initial condition is proposed. In the proposed method, the cutoff frequency of the filter phases in along a predefined profile from a high value to a low value on the time axis. The high cutoff frequency at the beginning part of cycle can suppress the influence of initial state error on learning. Experimental results show that this method can effectively handle initial position offsets.
