The break away and break in points can be on the real axis D. The break in point is always at a finite zero E. The break in point can be complex

1.Sketch the output voltage against time diagram for the values given in Q4 in the following.  Vref = 2 V, Vs = 10 V R1 = 1000 Ohms R2 = 10,000 Ohms cases: a) Vin is a sine wave with peak-to-peak voltage of 8 V and period of 5 ms. b) Vin is a sine wave with peak-to-peak voltage of 4 V and period of 5 ms. Answers from question 4: Vth1: -1.091 V Vth2: -2.909 V Vsym: 1.818V

0.02 (e) The responses in the figure below are for a unit step change in the disturbance with just P-control. One of the responses used a controller gain of Ke = 5 and the other used a controller gain of Ke = 8. Match the controller gains with the responses. Response to a Unit Step Change in Disturbance With P-Control 0.07 Response 1 --- Response 2 0.06 0.05 H 2 0.04H S 0.03 0.01 5 10 15 20 Time (min) (f) The responses in the figure below are for a unit step change in set point with a PI controller. The gain is the same for both responses but one response uses an integral time of ti = 1 min and the other uses an integral time of t = 2 min. Match the integral times for the PI controllers with the responses. r Response to a Unit Step Change in Set Point With Pl-Control 1. Respanse 1 --- Respanse 2 1.4 1.2 0.8 O 0.6- 0.4 0.2H 10 15 20 Time (min) (h) Determine the missing information for the sensor system in the following table. The output for the sensor system is a mA signal. Range Zero…

Please answer question 6, why is it that option?

Construct the Signal Flow Graph for the block diagram shown in Figure 1 below. G5 GI G2 G3 G4 H2 H3 Figure 1 : Block diagram for Assignment 1

Chose True or False * True False If a system is subjected to step input, the type of static error coefficient performs the function of controlling steady state error is position. If a type 1 system is subjected to parabolic input, the value of steady state error will be zero . The elements of rotational motion are the Mass, Spring, Friction. the notation represents the feedback path in closed loop system is c(t). The output signal is fed back at the input side from the Summing point. In an integral controller the output is proportional to integral of input. Two loops are said to be non- touching only if no common Branch exists between them. In block diagram representation, the lines connecting the blocks, known as branches. Order of the system can be determined from the e forward path transfer function of the system. A system with transfer function 1/Ts+1, subjected to a unit step input to reach 63.2% of final value, The value of t is T/2.
