An optimal filter is designed specially for dq transform used in the voltage mea-surement of transfer switch,which is composed of lower-order notch filter and lower-order low pass filter with higher cut-off frequency in series.Its transfer function is presented by theoretical derivation.If the order is same,it is better in measuring the positive sequence of fundamental amplitude than the average filter and the low-pass filter.

In order to study vector-valued optimization problem, in chapter 5, a class of vector -valued function, that is, uniformly same-order set-valued function is introduced , which includes the separated functions as its proper subset; without hypothesis of convexity, new minimax theorem and saddle point theorem for uniformly same-order set-valued function are established. Next, by employing Ky Fan\'s lemma and H-KKM mapping , several existence results for generalized vector equilibrium problem established.
