# QUESTION OF CONTROL SYSTEM?

SOLVE PLS

Consider the system whose governing equation is y¨(t)+2y(t)=u(t) . The input for which the system output would be unbounded is1sin(2t)cos(2–√t)sin(t)

Consider the system whose governing equation is y....(t)+6y¨(t)+9y(t)=u(t) . The system output would be unbounded for

only u(t)=1

only u(t)=cos(3t)

any bounded input

only u(t)=cos(9t)

Consider the system whose governing equation is y¨(t)−2y˙(t)−3y(t)=u(t) . The system output would be unbounded for

only u(t)=1

only u(t)=cos(3t)

only u(t)=sin(t)

any bounded input
