| Summary: | 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.
