K G(s) The plant transfer function is given by G(s) = 10 (s + 2)(s + 10) You want the system to have a damping ratio of 0.3 for unit step response. What is the value of K you need to choose to achieve the desired damping ratio? For that value of K, find the steady-state error for ramp input and settling time for step input. Hint: Sketch the root locus and find the point in the root locus that intersects with z = 0.3 line.arrow_forward
- Create the PLC ladder logic diagram for the logic gate circuit displayed in Figure 7-35. The pilot light red (PLTR) output section has three inputs: PBR, PBG, and SW. Pushbutton red (PBR) and pushbutton green (PBG) are inputs to an XOR logic gate. The output of the XOR logic gate and the inverted switch SW) are inputs to a two-input AND logic gate. These inputs generate the pilot light red (PLTR) output. The two-input AND logic gate output is also fed into a two-input NAND logic PBR PBG SW TSW PLTR Figure 7-35.

For this question, We define the settling time as the period of time it has taken for the output to settle into a steady state - ie when your oscillation first decays (aka reduces) to less than approximately 1/20 (5%) of the initial value. (a) Settling time = 22 μs Your last answer was interpreted as follows: Incorrect answer. Check 22 222 What is the peak to peak output voltage (BRF_OUT pp) at the steady state condition? You may need to use the zoom function to perform this calculation. Select a time point that is two times the settling time you answered in the question above. Answer to within 10% accuracy. (a) BRF_OUT pp= mVpp As you may have noticed, the output voltage amplitude is a tiny fraction of the input voltage, i.e. it has been significantly attenuated. Calculate the attenuation (decibels = dB) in the output signal as compared to the input based on the formula given below. Answer to within 1% accuracy.…arrow_forward
