碩士 === 國立成功大學 === 航空太空工程學系碩博士班 === 91 === The performance of the sliding mode controller realized by a digital computer will be limited due to the sampling frequency and the mechanism of sampling and hold process. Therefore, even without disturbance and uncertainties, the goal of the control system may not be achieved. In some cases it may result in system instability and chattering. On the other hand the robustness and invariance properties can not be guaranteed as the continuous time case. In this thesis Iterative Learning Control concept is introduced to improve the performance of discrete sliding mode control system. With the proposed algorithm, the resulting system performance can be improved and the chatting effect can be suppressed. The effectiveness of the learning process is illustrated by study cases.
