= 3. What steady-state error can be 1. A system has Kp (i.e., position error constant) expected for the input 8 u(t)? Answer: 2. The closed-loop transfer function of a unity feedback system is given by C(s)/R(s) = 1/[ts+1], then the system velocity error constant K, is (a) t (b) 1/t (c) 1 (d) ∞ (e) 0. Answer: 3. A unity feedback system with forward transfer function G(s) = 1/[s²(s+1)] is subjected to an input r(t) = K1 + K2t + 0.5 t. Then, the steady-state error of the system is (a) o (b) 1 (c) 0 (d) None of the above answers (a), (b) and (c) is correct. %3D Answer: 4. Consider a unity feedback control system with the PI controller F(s) =K + K/s and plant G(s) = 2/(s+4). What value of the integral gain K1 should you choose system has the velocity error constant K, = 40? that the Answer: 5. The forward transfer function of a control system has no zero and three poles at 0, 0, and -5 and the feedback transfer function has one single zero at -1. What is the system type? Answer: 6. A unity feedback system has open-loop transfer function G(s) = K/[s(s+1)(s+2)], K > 0. Find the value of K that results in oscillatory response to step input. %3D Answer:
