Control Systems The input-output relationship of a linear time invariant continuous time system is given by r(t) = d²c(t)/dt² + 3 dc(t)/dt + 2 c(t) Where r(t) and c(t) are input and output respectively. What is the transfer function of the system equal to? 1/(s² + s + 2) 2/(s² + 3s + 2) 1/(s² + 3s + 2) 2/(s² + s + 2) 1/(s² + s + 2) 2/(s² + 3s + 2) 1/(s² + 3s + 2) 2/(s² + s + 2) ANSWER DOWNLOAD EXAMIANS APP
Control Systems When deriving the transfer function of linear element both initial conditions and loading are taken into account. initial conditions are assumed to be zero and the element is assumed to be not loaded. initial conditions are assumed to be zero but loading is taken into account. initial conditions are taken into account but the element is assumed to be not loaded. both initial conditions and loading are taken into account. initial conditions are assumed to be zero and the element is assumed to be not loaded. initial conditions are assumed to be zero but loading is taken into account. initial conditions are taken into account but the element is assumed to be not loaded.
