In this paper, a new predictive control algorithm considering the parameters of series active filter has been proposed to improve the performance. By using the proposed control scheme, the current ripple drastically reduced and an improved steady state performance can be obtained, The proposed method has another advantage in the size and cost by excluding additional passive filters The validity of the proposed method will be proved by the computer simulation.<br/> <br/>

Milton's earlier sonnets describe the question of his identity as poet and his anxiety of the unsatisfied achievement in the literary life. He, in both the period of his literary exercise and prose, wrote 23 sonnets, one canzone and one "sonetto caudato". His earlier sonnets include 2 sonnets of English version, 5 sonnets of Italian version and one canzone of Italian version. These poems show us the relationship between poetry and poet, and his self-conscious anxiety in the period of literary exercise. Milton, in the earlier sonnets, followed the Italian tradition of sonnet, that is, that of Dante and Petrarch, and announced that he was destined to be a poet. This study excludes the sonnets written in the period of his literary prose(1640-1660), in which Milton wrote his political sonnets that made him famous as a sonneteer.

A new dead time compensation method using time delay control approach is presented. The dead time m switching pattern cause the voltage distortion and it can be considered as the disturbance voltage.<br/> In this paper, the disturbance voltage is estimated using time delay control and the estimated disturbance voltage is summed with voltage command in predictive current control by a feed-forward<br/> The proposed scheme is Implemented on a PMSM and the effectiveness is verified through comparative simulation.
