碩士 === 國立中山大學 === 電機工程研究所 === 84 === In this paper, the Sigma Adaptive Sliding Mode Control (SASMC) which is combination of Sliding Mode Control (SMC) and sigma adaptive law for the nonlinear system is developed. The proposed SASMC for the nonlinear systems can overcome the drawbacks due to SMC. It can achieve a smaller mean tracking error than that of SMC, suppress chattering due to SMC, improve transient response due to modeling error, and reduce the gain of the controller. We will compare SASMC with SMC for specific nonlinear vector systems and scalar systems. The simulations and analyses will show that SASMC for the specific nonlinear systems can overcome the drawbacks resulting from the use of SMC.
