1. explain low stability can be determined from bode plot ?
2. sketch the bode for a unity feed back system characteristic by the open loop transfer funtion
K(1+0.25s)(1+0.025s)
G(S)= -----------------------
s^2(1+0.01s)(1+0.005s)
show that system is conditionally stable & range for which system is stable?3. explain niguist stability critesion?
4. what is compensation ? what are the different types of compensation?
5. riscuss lag-lead compensetion & design the transfer funtion for this compensetor?
6. write the produser for constructing polar plot sketch polar plot for the transfer funtion
6
G(S)= ------------------
(s+1)(s+2)
7. state the steps for bode plot? sketch the bode plot & determine gain cross one frequency,phase cross frequency ,GM.PM & stability of system
10
G(S)= -------------------
s(1+s)(1+0.02s)
8. write the procedure for calculation of transfer funtion for magnitude plot & find the transfer funtion of the system show bode in
