EE321, Spring 08 Homework 4 Problem 16 W c 1 2 5 2 cos 2 θ rm () + i 2 = T e 2 sin 2 θ rm i 2 = Problem 17 P λ 1 Pi 2 0.8 i 1 i 2 0.2 5x + = P λ 2 Pi 1 3i 2 0.8 + = where P is used for partial. Clearly the two partial derivatives are not equal and so the system description is not feasible Problem 18 We may express the system as λ 1 λ 2 5 7 2 + 7 2 + 2 i 1 i 2 = which is of the form λ 1 λ 2 L i 1 i 2 = where L is independent of both current and flux linkage. Thus, this system is magnetically linear.
