Why don't you compute the closed-loop transfer function (with a PID controller) and then apply Routh's criterion. It will tell you whether you will be able to stabilize your system with a PID controller. In case, as the 'sisotool' tool error says, PID controller is not able to stabilize the system (no combination of Kp,Kd,Ki is making all the roots stable) then I would recommend switching to other control methods like LQR.
