Design of autopilot with Pole placement and State-Observer Feedback

A autopilot designing method with Pole placement Method and State-Observer Feedback is proposed. State feedback gain via pole placement is designed by selecting a suitable root of closed-loop transfer function. With poles placement method full-order state observer with one or two measurable outputs are designed respectively. By comparing time-domain outputs of the two observers, It is concluded that, observer with two measurable outputs can be more accurate in the observation on the original system state under the condition of guaranteeing Filter characteristics.
