SULIT (NMJ32804) - 6- (ii) Based on the Bode diagram in (i), estimate the values of gain and phase margins, and label the gain and phase margins on the diagram. (Berdasarkan lakaran Bode dalam (), anggarkan nilai jidar untung dan jidar fasa, dan tandakan jidar untung dan jidar fasa di atas lakaran tersebut.) (C4 / 10 Marks / Markah) Determine the stability of the closed loop system based on the gain and phase margins in (ii). (Tentukan kestabilan sistem gelung tertutup tersebut berdasarkan jidar untung dan jidar fasa dalam (ii).

(a) Based on the Bode plot in Figure 3, (Berdasarkan plot Bode dalam Rajah 3.) (0) What is the order of the system? [Apakan tertib sistem tersebut?] (C27 5 Marks / Markah) (ii) Does the system have any zero? (Adakah sistem tersebut mempunyai sebarang sifar?) (C275 Marks / Markah) Estimate the resonant peak magnitude and frequency (Anggarkan magnitud puncak dan frekuensi resonan] (C2 / 10 Marks / Markah) Note: Give justification for your answers in (i) and (ii). [Nota: Berikan justifikasi bagi jawaban anda dalam (i) dan (ii).) (b) The forward path transfer function of a unity feedback temperature control system is given as follows. [Fungsi pindah laluan hadapan dengan suapbalik unit kepada satu sistem kawalan suhu adalah seperti berikut.) K(8 + 20) G(s) = s(s? + 8s + 25) (i) Draw Bode diagram of the system for K = 1.25 (using straight line approximation) [Lukiskan gambarajah Bode sistem tersebut untuk K -1.25 (menggunakan anggaran garisan lurus)] (C4 / 60 Marks / Markah) (Note: Use semilog paper in Appendix 1 for your Bode plot and attach the plot to your answer script.) [Nota: Gunakan kertas semilog dalam Apendiks I untuk lakaran Bode anda dan kepilkan lakaran tersebut dengan kertas jawapan anda) ...6.
