| Summary: | 碩士 === 國立成功大學 === 航空太空工程學系碩博士班 === 93 === In recent years there is a great deal of effort made on the optimal and feedback control of the molecular system. But no studies have ever been tried to control the molecular motion with the LMI (Linear Matrix Inequality) control theory. In this thesis, we propose a LMI-based robust controller for the molecular motion system. Taking the expectation of molecular motion, we can derive a classical equation of motion from which, we then design H2,H∞ and H2/H∞、 controller for molecular systems with certainty. Finally, we use the LMI toolbox in matlab to simulate the result, and compare the performance of different control designs under different excitation conditions.
