The mechanical segment of a MEMS is a second-order system with its poles being -2 and -4. A proportional plus derivative controller defined by the constants KP and KI, and a proportional feedback sensor defined by Ks are also connected with the plant in a feedback control system. Determine the values of KP, KI, and Ks that render the system stable, marginally stable, or unstable.
