Department of Mechanical Engineering MICHIGAN STATE UNIVERSITY ME457: Modeling of Mechatronic Systems /hw_08.doc Page 1 of 4 Problem Set #8. Position Control. As an emerging engineering systems dominator, you are now in a position to control. To demonstrate your capability, please focus on the radar pedestal unit shown in Figure 1 below. One goal is to combine multi-port and block-diagram modeling of an engineering system that has both power and control subsystems. The control system positions the radar cone about a vertical axis. (A separate control system, not considered here, controls the elevation angle of the radar cone.) The radar unit is mounted on a large ring gear that provides both a support base and a means for applying a driving torque. The drive motor acts through a shaft and a pinion gear coupled to the ring gear. The motor input for control is the field voltage. The electric power to turn the pedestal actually comes through the armature port of the motor, which is modeled below as a special
