- 1. Consider a negative unity-feedback control system whose plant transfer function is type- 1. Suppose you want to build a lead compensator so that -3 ± 5j are dominant poles. You observed that the angle deficiency at the desired dominant pole is 50°. Compute a 's+b' and b of the lead compensator (s+ 2) so that the error constant Ky is maximized. In other words, design the lead compensator in a way so that the steady-state error for ramp input is minimumarrow_forwardEXAMPLE 8.12 The E-MOSFET of Fig. 8.40 was analyzed in Example 7.10, with the result that k = 0.24 × 103 A/V², VGS = 6.4 V, and ID = 2.75 mA. a.
