Parameters of the following transfer function are given as: k=3.1, a=9.8, and b=4.2, calculate the gain constant K of the control system. (please keep four digits after decimal point)𝑇𝐹=𝑘𝑎𝑠+𝑏

A system described by the transfer functionis stable.  The constraints on 𝛼 and k are,Select one:a. 𝛼 < 0, 𝛼𝐾 > 3b. 𝛼 > 0, 𝛼𝐾 < 3c. 𝛼 < 0, 𝛼𝐾 < 3d. 𝛼 > 0, 𝛼𝐾 > 3

Determine the voltage gain, input, and output impedance with feedback for voltage-series feedback having A= -100, Ri = 10 kΩ, and Ro = 20 kΩ for feedback of (a) β= -0.1 and (b) β= -0.5.

你怎样用MATLAB得到response graph，当分析一个负反馈回路，使用pid串联，且the step time=3,initial value=0,final value=20,sample time =0.05, the process transfer = 49/(12s^2+8.4s+49), the feedback transfer = 1.5/(0.5s+1.5), the gains Kp = 0.3, Ki = 2.4 , Kd=0.01, 怎样出入到MATLAB的命令窗口

Given a unity feedback system that has open loop transfer function. Compute the gain value K that makes the closed-loop system have a double pole. Also compute the location of the double pole.
