二、 教育部政務次長范巽綠於2019年召開的新住民語文課程記者會中表示, 108課網將7國東南亞新住民語言納入國小「必選」,讓臺灣開創全球先例。但此政策也引發部份家長質疑的聲音,例如「東南亞語列為必選,不會排擠英文學習、動搖中文地位嗎?」;或是「母語在家跟媽媽學就好了, 為什麼還要在學校上課?」等說法。請說明
(2)對於家長的擔憂與說法,你的想法為何?(15%)

Question 1.(20%、5% for each sketch)The pole/zero plots of four transfer functions G1(s) to G4(s) are shown in Figure 1. Sketch the step response of each transfer function. On your sketches, you should show important details of the responses. such as the overshoot, undershoot, steady state, etc. if any. Missing any important detail will result in mark deduction.

(a) (10%) Determine all triples (uq, uq, iq) that are consistent with an equilibrium inductor current iq = 0.3, where uqand uq denote equilibrium values for the source voltage and the capacitor voltage.
#471449
(b) (10%) For the equilibrium (uq, uq, iq) = (0.5, 0.5, 0.4), linearize the governing equations and derive a transfer function model to relate the Laplace transform △U(s) of δu(t) = ข(t) -ขq (as an output) and the Laplace transform △u(s) of δu(t) = u(t) - uq (as an input). Is the transfer function stable?
#471450
(c) (10%) For the transfer function identified in (b), calculate the response of the transfer function when δu(t) =sin(t).
#471451
Question 3(10%) Consider a standard negative feedback system shown in Figure 3, where. Determine how many seconds loop delay τ> 0 can be tolerated if a phasc margin of more than 45* is required in the presence of such delay.
#471452
Question 4(15%) Consider a standard negative feedback system shown in Figure 4, where the plantand the compensator . Find the positive compensator parameter values K > 0, such S+4 that the following conditions both hold: (i) the closed-loop is STABLE; and (ii) the closed-loop impulsc response has a mode that decays SLOWER than.
#471453
(a) (10%) Explain why a lag compensator (e.g., a PI controller) can NEVER stabilize G.
#471454
(b) (15%) Find a PROPER controller C such that the following conditions both hold: (i) the closed-loop is STABLE; and (ii) the response of the closed-loop system to any step input always has ZERO steady state error.
