the open loop transfer function of a unity feedback control system is given by G(S)=K/(S+2)(S+4)(S^2+6S+25). by applying the routh's criterion discuss the stability of the closed loop system as a function of K.determine the value of K which will cause sustained oscillations?
a unity feedback control system is characterized by the open loop transfer function G(s)= K(S+13)/S(S+3)(S+7). using routh's criterion calculate the range of values of K for the system to be stable?
the openloop transfer function of a unity feed back system is given by G(S)=K/S(ST+1) where K and T are positive constants. by what factor should the amplifier gain be reduced so that the peak overshoot of unit-step response of the system is reduced from 75% to 25%?

sir may i know the relation between amplifier gain and peak over shoot...? and hint for 4th problem in 4th unit...
amplifier gain is K and peak overshoot is e^-pi zeta/sqrt(1-zeta^2).find closed loop transfer function gh/1+gh and find peak overshoot for both percentages and solve the equations to obtain K.
what are dominant roots in time domain response sir??? it is given in 2nd prob of unit 3.
what is the meaning of sink mode? sir.
how does the step input becomes stable sir????
