| Summary: | 碩士 === 國立成功大學 === 航空太空工程學系 === 105 === The design of feedback control is to improve system behavior by placing the poles. There are system behaviors we want to improve, one is properly to allocate the output response with the input requirements, another is to increase robustness of the controller and the other is to have the system output follows the given command. Among them, the first two behaviors can be achieved by using linear quadratic optimization design, but the feedback control law, which is generated by using linear quadratic optimization design, is difficult to achieve. Therefore, we develop the output feedback realization of state feedback controller. However, the controller gain is too large to copy state feedback robustness. For this problem, this thesis proposed modified output feedback design to reduce the controller gain and the controller robustness to reach state feedback design. Moreover, even the linear quadratic optimization design can’t reach command following. In this thesis, we even add the integral control loop into output feedback design. As a result, the three goals of feedback control can be competed at the same time.
