碩士 === 國立臺灣科技大學 === 機械工程系 === 105 === When dealing with control problems, there are inevitable discrepancies between the actual system and mathematical models. Through proper controller design, these discrepancies can be reduced or can have less influence, thus the control goal can be achieved. This research proposes a control methodology for a class of single input single output nonlinear time variant systems with various uncertainties and disturbances. This control methodology combines many traditional control strategies, such as feedback linearization, sliding control, adaptive control, and function approximation technique based adaptive control. On the other hand, this methodology alleviates the singularity problem that usually happen when the bounded uncertainties appearing on the input channel.
