Question

Miller compensation results in one of these things moving up in frequency while another moves down in frequency, in an effect named for “splitting” these things. In MATLAB, the “place” function computes a gain matrix K that places these things at given locations. In the state-space representation, these things correspond to eigenvalues of A, the system matrix. These things are (-5[1])represented by X’s while their counterparts are represented by O’s in a graphical representation (-5[1])of a transfer function. The number of (15[1])counterclockwise encirclements of “negative one plus j zero” must equal the number of unstable open-loop examples of these things to satisfy the (*) Nyquist stability criterion. A system is stable if all of these things have negative real part, or equivalently (10[1])if they are in the left half of the s-plane. For 10 points, name this term from complex analysis that, for a function f, denotes a zero of the function 1 over f. ■END■ (10[1]0[3])
