PLEASE GIVE THE FULL DETAILS OF THE STEPS ON EACH QUESTIONS SO I COULD FOLLOW UP YOUR WHOLE EXPLANATIONS.
PLEASE WRITE THE STEPS ON SOLVING THIS EXAMPLE
EX) STEP 1, STEP 2, ETC
HANDWRITING IS OKAY AS LONG AS IT IS READABLE.
IF YOU HAVE USED THE EQUATIONS OR CONCEPTS, PLEASE STATE IT CLEARLY WHICH ONE YOU HAVE YOU USED SO I COULD FULLY UNDERSTAND THE DETAILS OF THE STEPS YOU HAVE DONE.
PLEASE DO NOT OMIT THE DETAILS OF STEPS AND CONCEPTS YOU HAVE USED, CLEARLY STATE IT!!
PLEASE GIVE POSSIBLE INTERVIEW QUESTIONS CAN BE ASKED IN Electrical and Control Systems: EX) FINDING BASIC LOOP OF THE SYSTEMS, FINDING GAIN ETC.Explanation / Answer
1) Difference between closed loop and open loop system with example.
2) They may ask mathematical modeling of mechanical and electrical system i.e spring, mass, friction etc.
3)you can also prepare rules of block diagram reduction techniques, signal flow graphs.
4) difference between transient response and steady state response.
5) difference between types of system and order of system
6) effect of different inputs on steady state error i.e step, ramp, parabolic etc.
7) analysis of second order system, effect of damping retio on position of closed loop poles, what is undamped, underdamped, critically famped, overdamped system explain with position of poles.
8) transient response specification.
9) stability analysis using Hurwitz stability criteria,.
10) difference between closed loop transfer function and open loop transfer function.
11) What is Root locus and why it is used.
12) you can also prepare effect of poles and zeros on Root locus.
13) what is bode plot analysis, and how magnitude and phase plot is dream from given transfer function, effect of poles and zeros on system. What is gain margin and phase margin? How gain margin and phase margin determine stability of system?
14) what is Nyquist stability criterion? And effect of poles and zeros on system, how gain and phase margin can be calculated from Nyquist plot.
15) what is constant phase loci or Not circle? What is Nichols chart and what is use of Nichols chart?
16) what is compensations? Explain different types. What is lead compensator, lag compensator, lead lag compensator?
17) difference between Root locus, bode plot, Nyquist stability criterion techniques?
18) what is P, I,D and PID controller explain.
19) you can prepare state space analysis, difference between state space and transfer function? Properties of state transition method.
20) PLC, Scada, , different programming language used in PLC, advantage of digital control system.
These are different types of questions which can be asked. But if you have time prepare more.
All the best.
