2. For the system represented by G(s) = s+7 (s+2)(s+3)(s+4) find the state-space representations: controllable canonical forms, observable canonical forms and Jordan form. 3. Draw a block-diagram of the system in Problem 2 based on each of the state-space representa- tions, such that all the blocks are either constant-gain blocks or free-integrator blocks whose transfer function is 1/s. And then identify their state variables in the diagrams.
