3. System Problems Problem! (4.5 grade steps) A discrete-time system has an input in and output vm). It is described by the constant coefficient difference equation Yin- ) xin - 11 + obyn - 2) + (yin - 2])* = *[n]+)#In - 11+ In -21 The desired operating point is = 0,7= 0. Find the transfer function (7) of the linearized system local to this operating system. Numerically determine and plot the step response of the system for steps of various sizes, from very small to moderately large. Find the steady-state valse and show how it changes with the size of the step input. Find the poles of the linearized system and confirm that it is stable. Grading Scheme: linearize gerade step) transfer function (0.5 grade step), numerical step response plot for varying input step size grade ster), steady-state values for trade step), poles and confirmation of stability (I grade step)
