Chapter 6, Problem 6.4P

5. Consider following feedback system. R(s) + 100 S+4 +1 Find the steady-state error for (i) step input and (ii) ramp input.

6. Find (i) settling time (Ts), (ii) rise time (Tr), (iii) peak time (Tp), and (iv) percent overshoot (% OS) for each of the following systems whose transfer functions are given by: a) H(s) = 5 s²+12s+20 5 b) H(s) = s²+6s+25 c) H(s) = (s+2) (s²+12s+20) (s²+4s+13) Use dominant pole approximation if needed.

7. Answer the following questions. Take help from ChatGPT to answer these questions (if you need). But write the answers briefly using your own words with no more than two sentences and make sure you check whether ChatGPT is giving you the appropriate answers in the context of class. a) Why do we need transient performance metrics? Name a few of such metrics. b) Define (i) settling time, (ii) rise time, (iii) peak time and (iv) percent overshoot. c) What is damping ratio? How does overshoot change with the change of damping ratio? When do we have zero overshoot? d) What is the criterion for selecting dominant pole in higher order systems? When dominant pole approximation is not valid? How will you calculate the transient performance metrics for the case when dominant pole approximation does not hold?

The transformer rating is 1200:2400 V @ 120 kVA. What is the apparent power provided by the source? What does this mean for the operation of the transformer?  Draw the power triangle at the source and calculate the power factor. The magnitude of the voltage source is given in VRMS.

I am looking for schematic ideas or recommendations for designing the required step-down system. Since the input is a 600V DC supply, a DC-DC converter may be necessary, as transformers are typically used for AC voltage. Key considerations would include: Voltage regulation: Ensuring a stable and consistent 120V DC output.Component selection: Choosing appropriate DC-DC converter modules, capacitors for filtering, and protective components such as fuses or circuit breakers.Lighting system: Recommendations on energy-efficient lighting options like LEDs, which work well with DC power and offer durability for railway applications.Thermal management: Addressing heat dissipation within the converter and lighting circuit.Safety and standards: Complying with safety regulations for electrical systems in railways. I would greatly appreciate detailed insights into the design process, including key circuit components and configurations, as well as any schematic diagrams or references.
